Technical documentation, parts identification, installation guides, and direct contact information for Empire Comfort Systems products.
Locate your model number on the rating plate, which is typically found inside the access panel on the front or bottom of your unit. Use the model number to reference our parts catalog, or contact our technical team directly with the model number for immediate part identification.
Request Parts Assistance →Thermostats (millivolt and electronic), pilot assemblies, thermopile generators, gas valves (Robertshaw, Honeywell, SIT), ignition modules, blower motors, remote control receivers, and burner assemblies — all available as OEM components.
We maintain parts support for many legacy Empire Comfort Systems models. If your unit was manufactured in the last 30 years, contact us with the model and serial number — our team can confirm availability or identify compatible alternatives.
Direct-vent models require a coaxial vent pipe through an exterior wall or roof. Minimum clearances vary by model — always consult the installation manual specific to your model number. In most jurisdictions, gas appliance installation must be performed by a licensed contractor.
For millivolt (standing pilot) models: (1) Turn the gas valve knob to PILOT, (2) depress and hold the knob while pressing the igniter button until the pilot lights, (3) hold for 30 seconds, (4) turn to the desired temperature setting. For electronic ignition models, refer to your specific model's operating guide.
Empire Comfort Systems millivolt heaters are compatible with standard millivolt thermostats. Select models include or are compatible with remote control kits. Contact us with your model number to confirm which thermostat or remote options are supported.
Ask About Thermostat Options →The most common cause is a weak or failed thermopile generator. A thermopile in good condition produces 300–750 mV; below 250 mV indicates replacement is needed. Secondary causes include a dirty pilot orifice, faulty gas valve, or blocked thermocouple tip.
Repeated cycling typically indicates an overtemperature condition triggering the high-limit switch. Check that vents are unobstructed, the blower is functioning, and clearance distances from combustible materials match the installation manual specifications.
If the pilot is lit but the main burner does not ignite when calling for heat, the gas valve may not be receiving sufficient millivolt signal from the thermopile. Test millivolt output at the gas valve terminals. Also verify that the thermostat circuit is complete.
