INSTALLATION
Air Shutters are required to increase or decrease the amount of air that is
mixed with the fuel before combustion. This will have an affect on how well
the fuel combusts and how the flame physically appears.
Low primary air will leave a taller, yellower flame while higher primary air will
leave a lower, bluer flame.
This setting is largely for appearance, however, not enough primary air may
lead to carboning, sooting or a flame that reaches the top of the firebox.
Situations that may require more primary air are; units that are burning
propane, units installed at higher elevations or units that are run on high
most of the time.
The L390E / HZI390E is equipped with an air shutter that is accessible from
outside the firebox and can be adjusted during operation.
Aeration adjustments should only be made after the unit has been on for 30
minutes to 1 hour.
Slide the Air Shutter Lever towards you to increase the primary air setting.
Slide the Air Shutter away from you to decrease the primary air setting.
Below you will see a chart showing the minimum primary air settings.
These are set from the factory, but due to fuel conversions or installation
conditions, the air setting may need to be adjusted.

GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply 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.
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 flat 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 specified on the safety label.
6) When finished reading manometer, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" flat screwdriver.
Note:Screw should be snug,but do not over
tighten.
