Assembling and Attaching
Brass Trim
1.
Remove packaging from remaining
three pieces of brass trim.
2.
Locate four brass screws, two adjust-
ing plates with set screws, and two
shims in the hardware packet.
3.
Align shim under adjusting plate as
shown in Figure 6.
4.
Slide one end of adjusting plate/shim
in slot on mitered edge of top brass trim
(see Figure 6).
5.
Slide other end of adjusting plate/shim
in slot on mitered edge of side brass
trim (see Figure 6).
6.
While firmly holding edges of brass
trim together, tighten both set screws
on the adjusting plate with slotted
screwdriver.
7.
Repeat steps 1 through 6 for other side.
8.
Place the assembled trim on front of
heater cabinet. Attach on top and sides
with four brass screws included in hard-
ware package (see Figure 7).
9.
Reattach front panel to heater if you are
going to mount the heater to the base.
Do not reattach front panel at this time
if you are going to mount heater to wall.

AIR FOR
COMBUSTION AND
VENTILATION
Today’s homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss in homes. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
PROVIDING ADEQUATE
VENTILATION
The following is excerpts from National
Fuel Gas Code. NFPA 54/ANSI Z223.1,
Section 5.3, Air for Combustion and Venti-
lation.
All spaces in homes fall into one of the three
following ventilation classifications:
1.
Unusually Tight Construction
2.
Unconfined Space
3.
Confined Space
The information on pages 5 through 7 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and win-
dows may provide enough fresh air for
combustion and ventilation. However, in
Confined and Unconfined Space
The National Fuel Gas Code (ANSI Z223.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m
3
per
kw) of the aggregate input rating of all
appliances installed in that space and an
unconfining space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m
3
per kw) of the aggregate
input rating of all appliances installed in that
space. Rooms communicating directly with
the space in which the appliances are in-
stalled*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a con-
fined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
* Adjoining rooms are communicating only
if there are doorless passageways or ventila-
tion grills between them.

WARNING: This heater shall
not be installed in a confined space
unless provisions are provided
for adequate combustion and ven-
tilation air. Read the following in-
structions to insure proper fresh
air for this and other fuel-burning
appliances in your home.
buildings of unusually tight construction,
you must provide additional fresh air.
Unusually tight construction is de-
fined as construction where:
a.
walls and ceilings exposed to the
outside atmosphere have a con-
tinuous water vapor retarder with
a rating of one perm (6 x 10
-11
kg
per pa-sec-m
2
) or less with open-
ings gasketed or sealed
and
b. weather stripping has been
added on openable windows and
doors
and
c.
caulking or sealants are applied
to areas such as joints around
window and door frames, be-
tween sole plates and floors, be-
tween wall-ceiling joints, be-
tween wall panels, at penetra-
tions for plumbing, electrical, and
gas lines, and at other openings.
If your home meets all of the three
criteria above, you must provide ad-
ditional fresh air. See
Ventilation Air
From Outdoors, page 7.
If your home does not meet all of the
three criteria above, proceed to
Deter-
mining Fresh-Air Flow for Heater Lo-
cation, page 6.
