Note: Remove all components blocking your access and
set aside.
A. Gas and Power Supply
• Locate the gas manual shutoff valve in the control area
in the bottom of the appliance. Turn the shutoff valve so
it is perpendicular to the gas line.
• If electricity has been brought to the appliance, shut off
all power by turning off the appropriate circuit breaker or
removing the fuse in the electrical panel.

1 Gas Conversion Instructions
Fire and/or Explosion Risk
• Shut off gas.
• Orifices must be replaced
WARNING
Failure to shut off the gas supply prior to disconnecting
gas supply could result in explosion of gas fumes.
Failure to replace the orifices could result in overheating
the gas appliance and possibly damaging your appliance
and your home.
B. Remove the Valve Assembly
Novus ND & NB Series
• Remove control access panel.
• Locate and remove the two wing nuts and the two wing
screws holding the valve plate assembly to the firebox
bottom.
• Grasp the valve plate assembly and slide to the left, then
down to disengage the valve plate assembly and clear the
wing studs in the rear.
• Rotate the valve plate assembly horizontally so the pilot
assembly comes out first from the valve compartment.
See Figure 1.1. Care should be used to not damage the
pilot when removing the valve plate assembly.
• Go to Section 1.D. Burner Orifice.
Note: Inspect the valve plate gasket at this time and
replace if worn or damaged. Contact your distributor/dealer
customer services department for replacement parts.

Valve Access
• Remove the control access panel so you can observe the
control area of your gas appliance.
• Remove the screen and glass frame assembly.
• Remove the Log Set (Designers)
- Remove two screws, one at each end of the grate.
- Pull the log/grate assembly up and off the burner.
• Remove the Log Set (CD Series)
- Lift the two top logs off the log set. See Figure 1.2.
- Remove the grate/log assembly by removing two
screws as shown in Figure 1.2. Lift and pull grate/log
assembly from front of firebox.
- Remove four screws securing the rear log (Figure 1.3).
Lift rear log and remove from firebox.
• Remove the main burner by removing four screws (Figure
1.3), one at each corner. Slide the burner to the left and
lift out. Set aside.
• Designer burners will lift straight up or slide forward then
up.

D. Burner Orifice - Novus ND/NB & Caliber CD-
Series
Use Table 1 and the existing rating label (located in the valve
compartment) to determine the correct orifice for your appli-
ance.
• For Caliber CD Series remove the two screws so air shutter
cover can be removed. See Figure 1.4.
• For Novus, Caliber & Designers: Using a 1/2 in. wrench,
remove the threaded orifice (see Figure 1.5), discard
and replace with the appropriate orifice. Make sure the
orifice is screwed on completely. Failure to have the
orifice completely screwed on will result in the valve plate
assembly not fitting together properly.
• Replace air shutter cover (CD Series).

C. High Altitude Installation
U.L. Listed gas appliances are tested and approved without
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000 ft,
it may be necessary to decrease the input rating by chang-
ing the existing burner orifice to a smaller size. Input rate
should be reduced by 4% for each 1000 ft above a 2000 ft
elevation in the U.S.A., or 10% for elevations between 2000
and 4500 ft in Canada. If the heating value of the gas has
been reduced, these rules do not apply. To identify the prop-
er orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4500 ft (in
Canada), check with local authorities.
D. Pilot Orifice
• Secure the bracket of the pilot assembly and loosen the
nut with a 7/16 in. wrench.
• Loosen the nut until the pilot hood becomes loose from
the pilot assembly. See Figure 1.7.
• The orifice is inside the base of the pilot assembly. See
Figure 1.8.
• Discard the existing orifice and replace with the pilot orifice
from this kit.

• (CD Series only) Replace the log set. The rear log must
be installed using the back set of holes are used when
converting to propane. See Figure 1.10.

2 After the Conversion
A. Adjustable Regulator
• To gain access to the valve regulator, open the control
access cover or panel.
• Follow the instructions steps 1-3 that are included with
the regulator. Save the label included in the kit for later
attachment to the appliance. See Figures 2.1 and 2.2.
B. Leak Check
• Turn on the gas supply to the appliance. All connections
must be tightened and checked for leaks with a
commercially available, noncorrosive leak check solution.
Be sure to rinse off the solution when done leak testing.
• Turn the gas control knob to the “PILOT” position. Push
the knob in all the way and hold. At the same time, push
in the red ignition button repeatedly until the pilot lights.
NEVER hold in the gas control knob for more than ten
seconds if the pilot does not light.
• Once the pilot lights, continue to hold in the control knob
for fifteen seconds. Release the gas control knob and it
will pop back up. Test for leaks at the pilot assembly.
• Turn the gas control knob to the “ON” position and turn
the switch on. Check for leaks around the valve and the
burner orifice with a commercially available, noncorrosive
leak check solution. Be sure to rinse off the solution when
done leak testing.
C. Pressure Check
The gas input, inlet pressure and manifold pressure
must be as indicated on the rating label located on the
bottom pan, near the valve.
• Verify that the valve gas control knob is set at the “PILOT”
position. This is important to prevent accidental gas leaks
during the pressure test.
• Using a small flat head screwdriver, completely loosen
the screw inside the pressure tap that you want to check.
The screw does not need to be removed.
• Place a 3/8 in. diameter tube from the manometer over
the pressure tap.
• Turn the gas knob to “ON” and the burner ON/OFF switch
to “ON”. The burner needs to be on to check the outlet
(manifold) pressure.
• Turn the burner switch to “OFF” and the valve knob to
“PILOT”. Disconnect the tubing and tighten the screw in
the pressure tap.
D. Verify Operation
• Turn the gas knob to “ON” and the switch to “OFF”.
• Verify that the burner lights.
• Turn the control knob clockwise and counterclockwise to
confirm the flame adjusts up and down.
• Let the appliance run for fifteen minutes, allowing the flame
to reach its height and color.

E. Check the Flame Patterns
Look at the flame of the burner, making sure the flames are
steady, not lifting or floating. The flame color should be blue
with yellow tips. The thermopile tip (standing pilot) should be
covered in flame. See Figure 2.3.

Thermopile
Flame covers top 1/2 in. of the
thermopile and thermocouple.

F. Air Shutter Adjustment (CD & Designer Series)
The air shutter adjusts the amount of air that mixes with
the gas as it enters the burner pan.
• Locate the wing nut underneath the firebox bottom.
See Figure 2.4. To close the air shutter, turn the wing
nut clockwise. To open the air shutter, turn the wing nut
counterclockwise. The air shutter is used to fine-tune
the flame as necessary for differences in altitude and
vent configuration. The air shutter fully open for LP
appliances.
• The appliance may produce a noise, caused from metal
expansion and contraction as it heats up and cools down.
This noise is similar to one that a furnace or heat duct may
produce and does not affect the operation or longevity of
the appliance.
Figure 2.4 Air Shutter Adjustment (Caliber & Designer Series)
H. Affix the Labels
• Attach the label included with the regulator kit on either
the valve or visibly adjacent to the valve. This label reads:
“This control has been converted to propane.”
• Attach the installer conversion label included with this
kit in a visible location on or near the appliance after the
appropriate information has been added to the label.
I. Reconnect Electric Supply
• Restore power by turning on the approriate circuit breaker
or putting a fuse back into the electrical panel.
Figure 2.5 Air Shutter Adjustment (Novus Series)
• Allow the appliance to operate 15-20 minutes. This will
give the flame time to reach its height and color before
making adjustments to the air shutter. As the air shutter
is closed, the flame should be taller and darker.
G. Air Shutter Adjustment (Novus ND/NB Series)
• Locate the burner tube in the valve compartment. See
Figure 2.5.
• Loosen the 1/4 in. nut using a nut driver or stubby
screwdriver. The air shutter should be adjusted to 3/8 in.
open for 30 & 33 in. appliances, fully open for 36 & 42 in.
appliances.
• Tighten the nut to lock the air shutter in position.
