WARNING
●
This conversion kit must be installed by a
qualified service agency* in accordance
with Navien’s instructions and all applicable
codes and requirements of the authority
having jurisdiction. The information in these
instructions must be followed to minimize
the risk of fire or explosion or to prevent
property damage, personal injury or death.
The 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.
●
Turn off electrical supply to the boiler and
close the manual gas shut-off valve to isolate
the boiler during conversion. Allow the boiler
to cool if it has been operating.
●
For propane boilers: The 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.
* A qualified service agency is any individual, firm,
corporation or company which either in person or
through a representative is engaged in and is responsible
for the connection, utilization, repair or servicing of gas
utilization equipment or accessories; who is experienced
in such work, familiar with all precautions required,
and has complied with all of the requirements of the
authority having jurisdiction.
In Canada
: The conversion shall be carried out in
accordance with the requirements of the provincial
authorities having jurisdiction and in accordance
with the requirements of the CAN‐B149.1 and CAN1‐
B149.2 Installation Code.
