CONVERT GAS VALVE
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit damage
The gas valve must be converted and pre−adjusted before
operating on propane gas. If not converted and pre−adjusted,
sooting and corrosion will occur leading to early heat
exchanger failure.
!
FIRE, EXPLOSION, ELECTRICAL SHOCK
HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
Gas supply MUST be shut off before disconnecting electrical
power and proceeding with conversion.
Do not use this kit if the gas valve in Figure 8 has a green label
on top of the valve. The green label on the gas valve is a special
low capacity gas valve. Refer to Specification Sheet for the
correct conversion kit.
