GAS PIPE 
PRESSURE TESTING
The appliance must be isolated from the gas 
supply piping system by closing its individual 
manual shut-off valve during any pressure 
testing of the gas supply piping system at test 
pressures equal to or less than 1/2 psig. (3.45 
kPa).  Disconnect piping from valve at pressures 
over 1/2 psig.
The manifold pressure is controlled by a regulator 
built into the gas control, and should be checked 
at the pressure test point.
Note: To properly check gas pressure, both 
inlet and manifold pressures should 
be checked using the valve pressure 
ports on the valve.
INSTALLATION 
9)  Connect the 2nd liner to the exhaust collar 
marked with an "E", seal connection with 
high temperature silicone. Secure with gear 
clamp.
NOTES:  
1)  Final gas connection should be made after 
unit is in place to avoid damage to line when 
pushing the unit into position.
2)  Mill-pac may be used instead of high 
temperature silicone and screws may be 
used instead of gear clamps at connections 
of liner to inlet and vent collars.
4)  Before installing the side brick panels, loosen 
the screws for the brick tabs enough so that 
you can slide the brick tabs on to the screws 
easily but that the tabs are secure.  For the 
location of the side brick tab screws see 
diagram 1. 
5)  Remove the brick tabs and slide the side 
brick panels into position.  See diagram 1.  
Install the brick tabs.  See diagram 2.
1)  Make sure the valve is in the "OFF" 
position.
2)  Loosen the "IN" and/or "OUT" pressure 
tap(s), turning counterclockwise with a 1/8" 
wide fl at screwdriver.
3)  Attach manometer to "IN" and/or "OUT" 
pressure tap(s) using a 5/16" ID hose.
4)  Light the pilot and turn the valve to "ON" 
position.
5)  The pressure check should be carried out 
with the unit burning and the setting should 
be within the limits specifi ed on the safety 
label.
6)  When fi nished reading manometer, turn 
off the gas valve, disconnect the hose and 
tighten the screw (clockwise) with a 1/8" fl at 
screwdriver. Note: Screw should be snug, 
but do not over tighten.

AERATION SYSTEM
The air shutter can be adjusted by moving the 
adjusting wire up or down. The wire is accessed 
through the bottom louver opening. Open the air 
shutter for a blue fl ame or close for a yellower 
fl ame. The burner aeration is factory set but 
may need adjusting due to either the local gas 
supply or altitude. 
Minimum Air Shutter Opening: 
 
3/16" Natural 
Gas
 1/4" 
Propane
CAUTION: Carbon will be produced if air shutter 
is closed too much. 
Note: any damage due to carboning resulting 
from improperly setting the aeration 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.
