Heater models are available for use with liquid propane, propane vapor, or natural gas fuels and utilize gas-certified solenoid valves. Brock-supplied regulators are standard on liquid propane models.
Brock’s full flame-wall burner provides top fuel-saving performance along with even heat distribution. This design is the most efficient style of burner available. Stainless steel baffles are standard.
Liquid propane heater models include a high capacity internal vaporizer. Vaporizer design features built-in flexibility to position the unit’s coil for optimum performance.
Large inspection door provides maximum accessibility to make it easy to service burner and vaporizer unit. Convenient sight ports on both sides of the heater make it easy to do visual checks
on burner unit operation.
Rodent-resistant conduit protects all exposed wiring, including ignition and flame circuit wires in the burner unit.
