Caution during installation
(1) Fuel inlet valve at the back of the heaters :
If a fuel valve is connected at the fuel inlet at the
back of the heater, adjust the position of the fuel
valve so that its control knob does not touch the
back guard.
(2) In the case of a standard installation (Flue pipe
directly behind the heater):
1. In order to install the back guard on a heater
already in operation, move the heater away
from the wall so that you can easily use a
screw driver to install the side pieces.
2. Install the top piece after the side pieces have
been attached, and the heater has been
reinstalled with the body clamp attached to the
wall.
(3) If using extension kits :
Install the back guards in accordance with Figure
2-13, page 30.
Caution in using the back guards
(1) Remove the top back guard when cleaning the
circulation fan assembly and rear of heater.
(2) To prevent overheating the Monitor, ensure that
the slits in the back guard are not blocked by
curtains or other obstructions.
