3. ASSEMBLING THE VENT SECTIONS
a. Attaching the Venting to the Appliance
To attach the irst vent pipe section to the appliance
collars, simply slide the lared end o the inner
lue o the vent section over the inner collar on the
appliance. At the same time, insert the outer lue
into the outer collar on the appliance. Push the
vent section into the appliance collar until all the
lances have snapped into place. Tug slightly on
the vent to con irm it has completely locked in
place.
b. Assembling Vent Sections
) Start the lared inner lue o section A over the
inner lue o section B.
2) Insert the outer lue o section A into the outer
lue o section B. See Figure 21.
Once both inner and outer lues are started,
press section A into section B irmly until
all lances have snapped into place. Tug
slightly on section A to con irm it has
completely locked into place. See Figure22.
c. Assembling Minimum Installation (MI)
Sections (not required for all installations)
MI sections are non-unitized so that they can be
cut to a certain length. To use these sections, they
must be cut to length rom the non-expanded end.
See Figure 23. They can then be attached by irst
connecting the expanded end o the MI inner lue
with the inner lue rom the adjacent vent section
and securing with three screws. The expanded
portion o the MI inner lue must overlap completely
with the untreated end o the adjacent vent section.
The outer lue can then be inserted into the
adjacent outer lue expanded end and attached to
the next vent section with three screws. The other
end o the MI vent section can then be attached by
itting a snap lock section to it and snapping it
together as normal.

F. UTILITIES
1. HIGH ALTITUDE INSTALLATION
For U.S. installation, appliances are tested and approved or elevations rom 0-2000 eet. When installing this appliance
at an elevation above 2000 eet, National Fuel Gas Codes require a decrease o the input rating by changing the
existing burner ori ice to a smaller size. Input should be reduced 4% or each 1000 eet above sea level. Check with
the local gas utility or proper ori ice size identi ication. Ori ices are available rom your Heatilator distributor.
For Canada, appliances are certi ied or elevations rom 0-4500 eet. When installing this appliance at an elevation
between 0-4500 eet in Canada, the input rating does not need to be reduced. When installing this appliance at an
elevation above 4500 eet in Canada, check with local authorities.
2. GAS LINE CONNECTION
The appliance is provided with a stainless steel lexible connector and manual shuto valve. See Figure 26. The
incoming gas line should be piped into the valve compartment and connected to the 1/2 FIP connection provided on
the manual shuto valve. All connections must be tightened and checked or leaks with a soap and water solution
or leak detector. Bleed the gas line to extract any air that may have been trapped inside the pipe. See Figure 27 to
connect the gas line. Gas connections may also be made by taking out the knockout in the bottom pan to allow
connection through the bottom o the appliance.
d. Assembling the Slip Sections
Slip sections should be snapped into the irst
mating piece, then expanded to their desired
length, making sure that a 1.5 overlap is
maintained between the two sections o the slip
section. The sections need to be secured by
driving two screws through the overlapping
portions o the vent. See Figure 24. This will
secure the slip section to the desired length and
prevent it rom separating. The slip section can
then be attached to the next section o vent.
e. Disassembling Vent Sections
(only if necessary)
To disassemble any two pieces o pipe, rotate
either section so that the seams on both pipe
sections are aligned as shown in Figure 25. They
can then be care ully pulled apart.

cover screw onto the propane gas regulator.
Step 4
a. Removing Logs
Follow the instructions or removing the glass, screen and logs on page 27.
b. Removing the Burner
Using a phillips screwdriver, remove the screws rom each corner o the burner. Care ully pull the burner to the
le t, o o the burner ori ice underneath. Set the burner aside.
Step 5
a. Pilot Orifice
Loosen and remove the screws that hold the pilot bracket to the pilot assembly ( our screws in all). Remove the
pilot bracket. Using a 1/2 wrench, loosen and separate the pilot nut rom the pilot assembly. See Figure 32. The
aluminum pilot may have to be bent slightly to separate the parts. Replace the natural gas pilot tube ori ice
(which will either have come out with the pilot nut or will be in the pilot assembly and have to be pulled out) with
the LP pilot ori ice supplied with the conversion kit. With the new ori ice in place, tighten the pilot nut to the pilot
assembly and reattach the pilot bracket to the pilot assembly and to the seal plate.

b. Burner Orifice
Completely loosen the nut securing the ori ice
with a 5/8 wrench (re er to Figure 33). Remove
the ori ice and replace it with the propane ori ice.
Tighten the nut.
c. To adjust the air shutter at the base o the burner
tube/neck, loosen the 1/4 screw using either a
1/4 nut driver or stubby screwdriver. Slide the

Figure 33 - Burner Orifice
d. Return the burner to its position on the ori ice
and secure it with our screws, one at each corner.
Test or leaks between the valve and burner with
the burner lit as indicated in Step6.
Step 6 - Leak Test
a. This is important! Propane (LP) gas is heavy. I
there is an incomplete gas line connection the
gas could leak and settle to the lowest point and
then accumulate. Such a situation could be
hazardous. Do not proceed until all connections
are checked and any leaks eliminated!
b. Turn on the gas.
c. Test all gas connections or possible leaks by
using a soap/water solution or Sni er (turn on
and calibrate the Sni er, then place the sensor
end o the sni er within 1/2 o each connection).
I the soap/water solution or Sni er indicates there
is a leak, tighten and seal the connection and
then retest.
d. Turn the position indicator to the PILOT position
and depress. Press the push button ignitor and
light the sa ety pilot. Continue holding the position
indicator in the depressed position until the pilot
stays lit (approximately 45 seconds). Test or leaks
at the pilot assembly using one o the methods in
Step 6c.
e. Turn the position indicator to the ON position
and test or leaks at the valve and the burner ori ice
using one o the methods in Step 6c.
Step 7 - Checking the Pressure
a. The gas input, inlet gas supply pressure and
mani old pressure must be as indicated on the
rating label located in the control area o the
appliance. Any other input, inlet pressure or
manifold pressure could cause your gas
appliance to operate other than intended and
could cause serious injury or property damage.
b. Inlet Pressure
Veri y that the gas valve is set at the PILOT
position. Veri y the inlet gas supply pressure by
loosening the screw located inside the inlet
pressure tap. See Figure 34. Connect a
Manometer to the inlet pressure tap by pushing
the Manometer hose over the pressure tap. Turn
the valve to the ON position and turn the burner
on (with wall switch, remote, etc.). I the inlet gas
pressure is incorrect, do not adjust without
speci ic approval and instruction rom the gas
supplier. Changing the inlet pressure may a ect
other appliances in the residence. When
inished, return the valve to the PILOT position,
disconnect the Manometer and tighten the inlet
pressure tap screw.
Figure 34 - Valve Pressure Test
c. Outlet Pressure
Veri y that the gas valve is set at the PILOT
position. Veri y the mani old pressure by
loosening the screw located inside the outlet
pressure tap. See Figure 34. Connect a
Manometer to the outlet pressure tab by pushing
the Manometer hose over the pressure tap. Turn
the valve to the ON position, ignite the
appliance, and ensure that the pressure is
between 3 and 4 water column (optimum
pressure is 3.5 WC) or natural gas and
