I'm a quality and compliance manager for an HVAC manufacturer. I audit gas heater installations in the field—roughly 200+ per year. In 2024, I rejected 6% of the installations I reviewed due to specification violations. Most of those failures were avoidable.
If you're a contractor, property manager, or homeowner preparing to install an Empire Comfort Systems gas heater, this checklist is for you. It's the same 7-point process I walk through on every audit. Some points will seem obvious. One of them, honestly, most installers get wrong. I'll point it out when we get there.
Quick aside: our support team gets questions that have nothing to do with heating. We've had people ask "what is a duvet cover," ask us to walk them through garage door cable replacement, and even request foil shaver recommendations. We redirect those fast. But when the question is about a gas heater we manufacture, I'm all in.
The 7-Point Quality Checklist
1. Verify the Rating Plate Before Anything Else
Every Empire Comfort Systems gas heater ships with a rating plate—a metal label on the side or back panel. It lists the model number, serial number, gas type, BTU input, and clearance specs. I'm honestly surprised by how many crews skip this step and assume they know what they're looking at.
Three things to confirm:
- Gas type. Natural gas and propane units look nearly identical but are not interchangeable. Using the wrong one is a safety hazard, not a minor mistake.
- BTU rating. A higher-BTU unit in a smaller space can overheat the room and the unit. The rating plate tells you what it was designed for.
- Serial number. Match it to the box and warranty registration. I've seen mismatched paperwork turn a warranty claim into a nightmare months later.
One more thing: if the installation is above 2,000 feet elevation, confirm the unit is configured for high-altitude operation. That spec is not always on the rating plate—check the manual.
In 2024, I rejected roughly 6% of the first production samples we reviewed due to rating plate inaccuracies. If I'm that picky on our side, installers should be equally picky on theirs.
2. Confirm Clearances to Combustibles
This is the point I said most installers get wrong. Clearance specs—minimum distances from the heater to walls, furniture, mantels, and flooring—are printed in the manual and on the rating plate. They're not suggestions.
In my first year as a quality coordinator (this was back in 2019), I made the classic assumption error: I assumed every contractor read those specs. Cost me a $22,000 redo when an installer mounted a gas heater four inches too close to a wall in a commercial space. The unit tripped its high-limit switch repeatedly until it shut down completely.
Read the clearance table for your specific model. Don't rely on "what we usually do." What was standard for an older model may not apply to the current one. The industry has changed a lot, and clearance specs have tightened accordingly.
3. Inspect the Gas Supply Line and Shutoff Valve
The gas line feeding your Empire Comfort Systems gas heater needs to be sized for the unit's BTU draw and the length of the run. A line that's too small delivers insufficient gas, which leads to poor combustion, soot, and nuisance shutdowns.
What I look for:
- Pipe size matches the manual's recommendation. Non-negotiable.
- Shutoff valve is within reach of the unit and operates smoothly. Check this before the unit is slid into position—I've seen valves end up completely inaccessible behind the heater.
- Leak test was performed at installation—not "trusted" because the connections looked tight. A soap-and-water test takes two minutes.
- Flexible connector (if used) is approved for gas appliances and not kinked.
I typically see one or two gas-line issues per quarter in field audits. It's not the most common problem, but it has the most severe consequences.
4. Check Burner and Log Placement
If you're installing Empire Comfort Systems gas logs, this step is critical. The logs aren't just decorative—they're positioned to produce a clean flame pattern and prevent soot buildup. Each log sits in a specific place, and the manual labels them for a reason.
Here's what I verify:
- Log position matches the diagram in the manual.
- Burner ports are clear of debris and packing material. You'd be surprised how often bits of shipping foam end up on the burner.
- Flame appearance after 15 minutes: steady blue at the base, yellow at the tips. Sooty orange flames mean the air-to-fuel ratio is off. If it looks wrong after 15 minutes, don't assume it will settle in. It won't. It will get worse.
- Glowing embers or vermiculite (if included) are placed per the manual—not piled up in a mound that could block gas flow.
I've seen properly installed gas logs run for 10+ years without a single service call. The difference between that and a sooty, smelly unit is almost always the initial setup.
5. Test the Thermostat and Safety Controls
Modern Empire Comfort Systems gas heaters use electronic ignition, which is a real upgrade over the standing pilot on older units. But new technology comes with different failure modes.
Walk through the sequence:
- Thermostat call: the unit should fire within a few seconds of the thermostat calling for heat.
- Shutdown: it should shut off cleanly when the setpoint is reached—not cycle erratically.
- Safety sensors: if the unit has an oxygen depletion sensor (ODS), verify it hasn't been bypassed. In Q3 2024, I found an installation where a technician had jumped the ODS because it "caused nuisance trips." That's a textbook safety violation.
- Thermostat compatibility: if the thermostat isn't the one that came in the box, confirm it's on the approved list. Smart thermostats are great—but only if they're compatible with your unit.
Trust me on this one: if a safety device is tripping during normal operation, the problem is the installation, not the device.
6. Verify Venting and Combustion Air
Gas heaters need fuel and air. The venting system handles exhaust; the combustion air supply handles intake. If either is compromised, you could get carbon monoxide issues in the worst case, or a unit that won't stay lit in the less-worst case.
For vented Empire Comfort Systems gas logs, check:
- Vent pipe is clean and unobstructed.
- Termination cap is installed per the manual, with proper clearance above the roofline.
- Combustion air openings are not blocked by boxes, insulation, or the homeowner's storage habits.
My experience here is based on roughly 200 field audits per year, mostly residential and light commercial. If you're working on a commercial-scale system or a custom venting setup, consult the engineering spec sheet—this checklist is a starting point, not the final word.
7. Complete the Documentation Trail
The last step gets skipped the most. Not because it's hard, but because it's paperwork. Which means it's actually important.
Verify:
- Warranty registration was completed (online or by mail).
- The owner's manual was left with the customer or property manager.
- Gas pressure readings from the install were recorded, if applicable.
- Local service contact info is included.
When something breaks, homeowners don't call us with a duvet cover question. They call saying "your heater stopped working." In most cases, the manual they never received would have helped them diagnose it. That paperwork is there on purpose.
If you're a contractor, take a photo of the completed installation and the rating plate before you leave. It's saved me in more than one dispute, and it's good practice for your own records.
Common Mistakes I See in the Field
Across my audits, a few patterns keep coming up:
- Assuming "standard" clearances apply. They don't. Each model has its own clearance table. Look it up.
- Skipping the leak test because the connections look fine. It takes two minutes. Seriously, two minutes.
- Over-sizing the burner. More heat isn't better if it exceeds the space's heat load.
- Blocking combustion air for aesthetics. I get that the vent grate isn't pretty. It's also not optional.
One thing I've learned over the years: the fundamentals of gas heating haven't changed—gas in, combustion out, safety controls in between. But the execution has transformed. As of January 2025, most new units in our line use electronic ignition and ODS sensors as standard. The old "set it and forget it" mentality doesn't work anymore. The equipment is smarter, but it expects more from the installation.
If you're installing a gas heater or gas logs from our line and something in this checklist doesn't match what you're seeing, call our support line. Unlike the foil shaver requests, this one we can actually help with.
