1.0 INSTALLATION INSTRUCTIONS
In planning the installation for the heater it is neces-
sary to determine where the unit is to be installed, the
type of flue system to be used (straight out, corner,
or elevated), and whether optional accessories (wall
switch or remote control) are desired. Gas supply
piping should also be planned. Refer to the appliance
data plate on the base pan of the heater for all gas
pressures and input rate information.
The heater can be mounted on any of the following
surface:
1. A flat surface (minimum 6 mm base).
2. Four (4) corner supports.
(Example: Four (4) concrete masonry blocks). These
supports must be positioned so they contact all four
(4) perimeter edges on the bottom of the unit.
Heaterframingcanbebuilt beforeor aftertheheater is
set in place. Framing should be positioned to accom-
modate wall covering and heater facing material. The
heater framing should be constructed of 2" X 4" (51 x
102 mm) lumber or heavier. The framing headers may
restonthe heaterstandoffs.Refer to Figure2 and Fig-
ure 4 for heater and framing reference dimensions.
NOTE: Not intended for heater insert.

1.1 INTRODUCTION
This model is designed to operate with all combustion
air being siphoned from the outside of the building
and all exhaust gases expelled to the outside of the
building.
WARNING: THIS UNIT IS NOT FOR USE WITH
SOLID FUEL.
These units MUST use the flue termination described
in the flueing section of the manual.
The control system for this model is an electronic ig-
nition type. It consists of a gas control valve/variable
regulator, a pilot/sensor/electrode and an ON/OFF
switch. The controls are located behind the access
door. Rotate the door down to open. See Figure 1.
Minimum inlet gas supply pressure for purpose of
input adjustment is 1.13 kPa for natural gas and 2.75
kPa for propane. Manifold (outlet) pressures should
be set at .8 kPa for natural gas models and 2.36 kPa
for propane models.

NOTES: 1. All distances are measured vertically or horizontally along the wall to a point
in line with the nearest part of the terminal.
2. Prohibited area below electricity meter or fuse box extends to ground level.
3. See clause 5.13.6.6 for restrictions on a flue terminal under a roofed area.
4. See Appendix J, Figure J1(a) and J2(a) for clearances required from a flue
terminal to a LP Gas cylinder. A flue terminal is considered to be a source of ignition.

1.2 FLUE SYSTEM APPROVALS
Thesemodelshavefluestartingcollarson boththe top
and the back of the unit. Depending upon the instal-
lation, decide which ONE set of starting collars will be
usedtoattach theflue system.The startingcollar seal-
ing cap must remain on the starting collar NOT used.
These models use SLP series direct flue components
whenusingthe TOP flue collars andDVP seriesdirect
flue components when using the REAR flue collars.
WARNING: YOU MUST NOT MIX DVP-SERIESAND
SLPSERIES COMPONENTS INANY FLUESYSTEM
CONFIGURATION.
Approved flue system components are labeled for
identification. NO OTHER FLUEING SYSTEMS OR
COMPONENTS MAY BE USED. Detailed installation
instructions are included with each flue termination kit
and should be used in conjunction with this manual.
Figure 5 below shows flue system components and
terminations.
Identifying Flue Components
The flue systems installed on this gas heater may
include one, two, or three 90° elbow assemblies. The
relationships of vertical rise to horizontal run in flue
configurations using 90° elbows MUST BE strictly
adhered to. The rise to run relationships are shown
in the flueing drawings and tables on the next few
pages.
WARNING: THIS GAS APPLIANCE AND FLUE AS-
SEMBLY MUST FLUE DIRECTLY TO THE OUTSIDE
AND MUST NEVER BEATTACHED TOA CHIMNEY

Installing Flue Components
A. On the REAR of the heater
1. Attaching the First Flue Component to the Start-
ing Collars:
To attachthe firstflue componenttothe startingcollars
on the rear of the heater:
• Make sure that the flue gasket supplied with the
heater seals between the first flue component and
the outer heater wrap.
• Slide the male end of the inner flue of the pipe sec-
tion over the inner collar on the heater. At the same
time, slide the outer flue over the outer collar on the
heater.Pushthefluesectionintotheappliancecollar
until all the lances (see Figure 29) have snapped in
place. Tug slightly on the flue to confirm that it has
completely locked into place.
Figure 29.
• Any 90º elbow installed directly onto the rear flue of
the heater MUST BE in a vertical position.
2. Assembling Flue Components
Insert the inner flue of section A into the flared inner
flue of section B.
Start the outer flue of section A over the outer flue of
section B (see Figure 30). Note: The end of the pipe
sections with the lances/tabs on it will face towards
the appliance.
Once both inner and outer flues are started, press
section A onto section B firmly until all lances have
snapped into place. Check to make sure they have
snapped together (see Figure 31) and the seams are
not aligned. Tug slightly on section A to confirm it has
completely locked into place.

Impaired Performance of Appliance
• Overlap pipe slip sections at least 38
mm.
• Screws must not exceed one inch
long.
• Pipe may separate if not properly
joined.
WARNING
NOTE: Make sure that seams are NOT aligned to
prevent unintentional disconnection.
For elbows that are changing the flue direction, two
screws minimum should be put in the outer flue at the
joint to prevent the elbow from rotating.
PROCEED TO STEP 4
(Install Support Brackets)

4. Install Support Brackets
For Horizontal Runs - The flue system must be
supportedevery1.5 mof horizontalrunby ahorizontal
pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the flue pipe.
• Nail the pipe supports to the framing members.
• Align the seam of the pipe and seam of the collar to
allow engagement. Rotat the flue to lock into place.
Use this procedure for all the components. See
Figure 32.
• Slide the gasket over the first flue section and place
itflushto theheater.Thiswill prevent coldair infiltra-
tion. High temperature caulk may be used to hold
the gasket in platce.
Figure 32. Adding Flue Components
B. On the TOP of the heater
1. Attaching the First Flue Component to the Start-
ing Collars:
To attachthe firstflue componenttothe startingcollars
on the top of the heater:
• Lock the flue components into place by sliding the
concentric pipe sections into the heater collar or
previously installed component end.
2. Continue Adding Flue Components
Tocontinue addingfluecomponents inaccordancewith
the pre-planned flue system configuration:
• Ensure that each succeeding flue component is se-
curelyfittedand lockedintotheprecedingcomponent
in the flue system.
For elbows that are changing the flue direction, two
screws minimum should be put in the outer flue at the
joint to prevent the elbow from rotating.
3. Assemble Slip Sections
• Slide the inner flue of the slip section into the inner
flue of the pipe section and the outer flue of the slip
section over the outer flue of the pipe section. See
Figure 33.
• Slide together to the desired length.

• Continue adding pipe as necessary following
instructions in “Assembling Pipe Sections.”
NOTICE: If slip section is too long, the inner and
outer flues of the slip section can be cut to the desired
length.
• Maintain a 1-1/2 in. (38 mm) overlap between the
slip section and the pipe section.
• Secure the pipe and slip section with two screws no
longer than 1/2 in. (13 mm), using the pilot holes in
the slip section. See Figure 34.
