A carbon monoxide (CO) detector is required in the same room as the appliance.

The gas line must be installed in accordance with all local codes, if any; if not, follow ANSI 223.1
and the requirements listed below.

A manual shutoff valve is required within 3' of the heater. It should be placed upstream of the flex
line (if used) and may be installed behind the access door inside the heater. ).

The heater and gas control valve must be disconnected from the gas supply piping during any
pressure testing of that system at test pressures in excess of 1/2 psig. For pressures under 1/2
psig, isolate the gas supply piping by closing the manual shutoff valve.

Leak test all gas line joints and the gas control valve prior to and after starting the heater.

This heater is designed either for natural gas or for propane (but not for both). Check the sticker
on the top of the gas control valve to make sure the correct fuel is used (see illustration on page
4).

Installation must be performed by a qualified installer, service agency or the gas supplier (In
Massachusetts a licensed plumber/gasfitter).

Gas Line Location


The gas inlet accepts a ½" MPT.

Gas Inlet Pressure


If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is
adequately adjusted, and the total gas load for the residence does not exceed the amount
supplied.

The supply regulator (the regulator that attaches directly to the residence inlet or to the propane
tank) should supply gas at the suggested input pressure listed above. Contact the local gas
supplier if the regulator is at an improper pressure.
