preVention
Never allow any part of your body to
contact the heat exchanger or the vent
piping.
If burner fails to shut off, turn off the gas
supply and contact your serviceman.
Never exceed manufacturers maximum
allowable pressure rating of attachments.
Do not allow any hoses to make contact
with the heat exchanger to prevent the
possibility of bursting. Avoid dragging the
hoses over abrasive surfaces such as
cement.
Use only manufacturer recommended
repair parts for your heater module.
In freezing temperatures, the unit must
always be warm enough to ensure there
is no ice formation in the unit. Do not
start the heater module without first
allowing the unit to thaw.
Do not operate the unit without all
protective covers in place or make any
adjustments without shutting off the
heater module, relieving pressure and
disconnecting the heater module from
the power source. Allow heater module
to cool down. Never assume the heater
module is safe to work on just because
it is not operating. It could restart at any
time!
