The boiler conversion must be done by a qualified installer or
service technician in accordance with these instructions and
must meet all local codes and requirements of the authority
having jurisdiction. The qualified installer or technician
performing this work assumes full responsibility for this
conversion.
It is important that you follow the conversion procedure in the
proper sequence. We have enclosed for your convenience
three conversion labels, one of which will be attached to the
inside of the boiler and one which will be placed near the
rating label on the outside of the boiler. One will not be used.
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 connecting 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.
STEP 2 – PVC & CPVC ONLY
Drill and tap a 21/64" diameter, 1/8" NPT hole into
exhaust piping 1 foot from unit to be used as a test port
for the combustion analyzer. See Figure 2.
This conversion shall be done by a qualified service agency in accordance with the manufacturer's instructions
and all applicable codes and requirements of the authority having jurisdiction. A qualified service agency is
responsible for the proper installation of this kit. The installation is not proper and complete until the operation
of the converted appliance is checked as specified in the manufacturer's instructions supplied with the kit.
