Installation & Service Manual
Check for gas leaks
Before starting the boiler, and during
initial operation, smell near the floor and
around the boiler for gas odorant or any
unusual odor. Remove the top access
panel and smell the interior of the boiler
enclosure. Do not proceed with startup
if there is any indication of a gas leak.
Use an approved leak detection solution.
Repair any leaks at once.
DO NOT adjust gas valve outlet pressure.
The gas valve is factory set for the correct
outlet pressure. This setting is suitable
for natural gas and propane, requiring
no field adjustment. Attempting to
alter the gas valve outlet pressure could
result in damage to the valve, causing
potential severe personal injury, death, or
substantial property damage.
⚠ WARNING
⚠ WARNING
Propane boilers only – Your propane
supplier mixes an odorant with the propane
to make its presence detectable. In some
instances, the odorant can fade, and the gas
may no longer have an odor. Before startup
(and periodically thereafter), have the
propane supplier verify the correct odorant
level in the gas.
