INSTALLATION
the setting should be within the limits specifi ed.
GAS INSERT AERATION
SYSTEM
The aeration adjustment rod is attached to the
air shutter which is located just above the orifi ce
bracket. The rod is used to adjust the aeration
on the main burner without having to take the
appliance apart.
The burner aeration is factory set but may need
adjusting due to either the local gas supply, air
supply or altitude.
Natural Gas:
3/8" (9.5mm) open
Propane:
3/8" (9.5mm) open
Note: Any damage due to carboning result-
ing from improperly setting the aera-
tion controls is NOT covered under
warranty.
Note: Aeration Adjustment should only
be performed by an authorized FPI
Installer at the time of installation or
service.
TEST FOR FLUE
SPILLAGE
A " spillage" test must be made before the
installed unit is left with the customer. Follow
the procedure below:
1) Start all exhaust fans in the home and then
close all external doors and windows in the
house.
2) Light the unit and set controls to maximum.
Turn fan off.
3) After fi ve minutes, test that there is a "pull" on
the fl ue by placing a smoke match, cigarette or
similar device which gives off smoke, in front
of the spill tube. To ensure a valid test, place a
scrap piece of sheet metal (or other noncom-
bustible material) between the spill tube and
the upper louver, this will prevent the natural
convection of the unit from interfering with the
test. See diagram 1.

Check for proper draft by placing a
match close to the draft check open-
ing. This should be checked after the unit
Diagram 1
The smoke should be drawn into the spill tube. If
the smoke is still not drawn into the spill tube, turn
the unit off and check for the cause of the lack of
draft. If necessary, seek expert advice.
For wind turbulent sites, a wind cap may remedy
the problem.
Note: The thermally activated safety switch will
sense the change in temperature and shut down
the gas valve in the event of a severe downdraft
or a blocked or disconnected vent. The switch
acts as a safety shut-off to prevent a build-up
of carbon monoxide. If the fl ue is blocked or
has no "draw", the switch will automatically
shut off the supply of gas within 5 - 10 minutes.
Tampering with the switch can result in carbon
monoxide (CO) poisoning and possible death.
If the heater turns off because of lack of draft
during the spillage test, check for the cause
and if necessary, seek expert advice.
The thermally actuated safety switch will auto-
matically reset after it has cooled off. The switch
will continue to cycle until the draft problem is
corrected. DO NOT BYPASS OR DISCONNECT
THIS SWITCH.
OPTIONAL
BRICK PANEL
1) Unwrap the brick pattern panels from the pro-
tective wrapping.
2) Remove the glass front if it is already installed.
3) Put the rear brick panel fl at against the back of
the unit.
Diagram 1
4) Before installing the side brick panels, loosen
the screws for the brick tabs enough so that you
can slide the brick clips on to the screws easily
but that the tabs are secure. For the location
of the side brick tab screws see Diagram 2.

5) Slide brick panel under brick clips, tighten screws
securing clips to complete installation.
