WARNING
It is very important that you carefully follow the
instructions below correctly. Death or serious injury
could result.
Note: Failure to do so will void your warranty.
STEP 1
Turn off all power to the unit. Shut the gas off with the
manual shutoff valve. Make sure that the gas supply is
connected. Check gas pressure and gas piping to assure
proper sizing to the boiler firing rate.
If connected to LP gas, it is recommended that you contact
your gas supplier to size the piping and the tank. It may also
be necessary to install a 100% lockup gas pressure regulator
of sufficient capacity to supply an adequate gas flow.
