F. ASSEMBLING THE ENT SECTIONS
1. ATTACHING THE VENTING TO THE
APPLIANCE
To attach the first pipe section to the collars, simply slide
the flared end of the inner flue of the pipe section over
the inner collar on the appliance. At the same time, insert
the outer flue 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 confirm it has completely locked in place.
2. ASSEMBLING VENT SECTIONS
a. Start the flared inner flue of Section A over the
inner flue of Section B.
b. Insert the outer flue of Section A into the outer
flue of Section B. See igure 21.
Once both inner and outer flues are started, press
Section A into Section B firmly until all lances
have snapped into place. Tug slightly on Section
A to confirm it has completely locked into place.
See igure 22.
Note: Squeezing the pipe slightly to fit may be necessary.
Note: Make sure that the seams are NOT aligned in
order to prevent unintentional disconnection.
3. ASSEMBLING MINIMUM INSTALLATION
(MI) SECTIONS
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 from the non-expanded end. See igure23.
They can then be attached by first connecting the
expanded end of the MI inner flue with the inner flue
from the adjacent vent section and securing with three
screws. The expanded portion of the MI inner flue must
overlap completely with the untreated end of the adjacent
vent section. The outer flue can then be inserted into
the adjacent outer flue expanded end and attached to
the next vent section with three screws. The other end
of the MI vent section can then be attached by fitting a
snap lock section to it and snapping it together as normal.

4. ASSEMBLING THE SLIP SECTIONS
Slip sections should be snapped into the first mating
piece, then expanded to their desired length, making
sure that a 1.5 overlap is maintained between the
two sections of the slip section. The two sections of
the slip section then need to be secured by driving
two screws through the overlapping portions of the
vent. See igure 24. This will secure the slip section to
the desired length and prevent it from separating. The
slip section can then be attached to the next section of
vent.
5. DISASSEMBLING VENT SECTIONS (only
if necessary)
To disassemble any two pieces of pipe, simply rotate
either section so that the seams on both pipe sections
are aligned as shown in igure 25. They can then be
carefully pulled apart.

Step 3
Using the regulator replacement kit, follow the instructions (Steps 1-3 that come with the kit). After completion of
Step 3, return to these instructions.
Remove the tamper proof cover screw from the natural gas regulator (using snap ring pliers) and install the cover
screw onto the propane gas regulator.
Step 4. Remove the Logs
ollow the instructions on page 27 of this manual.
Step 5. Remove the Burner
Using a phillips screwdriver, remove the screw at the right end of the burner tube. Carefully pull the burner to the
right, off of the burner orifice underneath. Set the burner aside.
Step 6. Remove the Pilot Orifice
Loosen and remove the two screws on either side of the pilot. Lift the pilot hood and orifice seal off the base plate.
See igure 32. Using needle nose pliers, remove the pilot orifice and replace it with the new orifice. Place the orifice

Step 7. Remove Burner Orifice
Completely loosen the nut securing the orifice with a 5/
8 wrench. See igure 34. Remove the orifice and
replace it with the propane orifice. Tighten the nut and
return all components to their original position. Test
for leaks between the valve and burner with the burner
lit as indicated in Step 9.
Step 8. Air Shutter Adjustments
To adjust the air shutter at the base of the burner tube/
neck loosen the ¼ screw, using either a ¼ nut driver
or stubby screwdriver. Slide the shutter fully open and
secure. See igure 34.
Step 10. Checking the Pressure
The gas input, inlet gas supply pressure and manifold
pressure must be as indicated on the rating label
located in the control area of 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.
Standing Pilot Models:
Verify that the gas valve is set at the PILOT position.
Verify the inlet gas supply pressure by loosening the
screw located inside the inlet pressure tap. See
igure35. 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.). If the inlet gas
pressure is incorrect, do not adjust without specific
approval and instructions from the gas supplier.
Changing the inlet pressure may affect other
appliances in the residence. When finished, return the
valve to the PILOT position, disconnect the
manometer and tighten the inlet pressure tap screw.
Outlet Pressure Verify that the gas valve is set at the
PILOT position. Verify the manifold pressure by
loosening the screw located inside the outlet pressure
tap. See igure 35. Connect a manometer to the outlet
pressure tap by pushing the manometer hose over the
pressure tap. Turn the valve to the ON position, ignite
the appliance (with the wall switch, remote, etc.) and
ensure the pressure is between 3 and 4 water column
(optimum pressure is 3.5 WC) for natural gas and
between 10 and 11 water column (optimum pressure
is 10.0 WC) for propane. If the outlet gas pressure is
incorrect, contact the gas supplier or Heatilator
Technical Service Department. When finished, turn the
valve back to PILOT, disconnect the manometer and
tighten the outlet pressure tap screw.
Do not leave the pressure too low or too high. This will
create a safety hazard!
Step 9. Leak Test
This is important! Propane (LP) gas is heavy. If 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.
Turn on gas.
Test all gas connections for possible leaks by using a
soap and water solution or sniffer (turn on and calibrate
the sniffer, then place the sensor end of the sniffer
within 1/2 of each connection). If the soap/water or
sniffer indicates there is a leak, tighten and seal the
connection and then re-test.
Turn position indicator to pilot position and depress.
Press the push button ignitor and light the safety pilot.
Continue holding the position indicator in the
depressed position until pilot stays lit (approximately
45 seconds). Test for leaks at the pilot assembly using
one of the methods above.
Reattach the burner tube onto the orifice and secure it
with a screw at the opposite end. Turn position indicator
to the on position and test for leaks at the valve and
burner orifice using one of the methods above.
