Direct Vent Propane Heaters — No Electricity Required

Yes. Combustion Research Corporation's Synergy Series heaters include a Millivolt Self-Energizing Standing Pilot with 100% shutoff that requires no external electrical supply. The heater generates its own ignition current from the pilot flame, allowing full operation — including safety shutoff — without any electrical connection whatsoever.

The Synergy Single Stage series is available in four BTU ranges: 30K–60K, 70K–100K, 110K–160K, and 175K–200K BTU. This range allows you to select the right output for spot or zone heating in small service bays up to total building heating in large industrial warehouses and aircraft hangars.

No. All Synergy Series models are designed with no direct venting required, meaning fewer or no roof penetrations are needed compared to conventional vented heaters. This significantly reduces installation complexity and cost, while also making them suitable for use in protected outdoor environments.

All Synergy Single Stage models are compatible with both Natural Gas (NG) and LP/Propane Gas. Gas inlet size is 1/2 inch FPT across all models. Minimum inlet pressure for LP/Propane is 11 inches WC, and the maximum inlet pressure for both fuel types is 14 inches WC.

Synergy Series heaters reach maximum operating temperature in less than one minute from ignition. This instant-on radiant heat is especially beneficial for intermittently occupied spaces like loading docks, service bays, and manufacturing work cells where continuous heating would be wasteful.

Yes. All Synergy Series heaters are CSA International Design Certified to ANSI/CGA Standards and meet ANSI Z83.20 / CSA 2.34 requirements. Every unit is factory pre-wired, pre-piped, and tested before shipment, and each includes a 1-year limited manufacturer's warranty with full technical support documentation available.
