GENERAL INSTRUCTIONS

THIS GAS FIREPLACE SHOULD BE INSTALLED AND
SERVICED BY A QUALIFIED INSTALLER to conform with

local codes. In absence of local codes, install the GB20 to
the current National Fuel Gas Code, ANSI Z223.1, or the
current CAN/CGA B149, Installation Codes.

The fireplace and its individual shutoff valve must be dis­connected from the gas supply piping system during any
pressure testing of that system at test pressures in ex­cess of 1/2 psig (3.5 kPa). The fireplace must be isolated
from the gas supply piping system by closing its individual
manual shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or
less than 1/2 psig (3.5 kPa).

When the fireplace is installed directly on carpeting, vinyl
tile or other combustible material other than wood floor­ing, the fireplace shall be installed on a metal or wood
panel extending the full width and depth.

If the optional fan or blower is installed, the junction box
must be electrically connected and grounded in accord­ance with local codes. In the absence of local codes, use
the current CSA C22.1 CANADIAN ELECTRICAL CODE in
Canada or the ANSI/NFPA 70-1996 NATIONAL ELECTRI­CAL CODE in the United States.

GENERAL INFORMATION

FOR YOUR SA TISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUAL­ITY! Maximum input for the GB20 is 17,000 BTU/h for natu-

ral gas and propane. When the fireplace is installed at
elevations above 4,500ft, and in the absense of specific
recommendations from the local authority having jurisdic­tion, the certified high altitude input rating shall be reduced
at the rate of 4% for each additional 1,000ft.

Minimum inlet gas supply pressure is 4.5 inches water
column for natural gas and 11 inches water column for
propane. Maximum inlet gas pressure is 7 inches water
column for natural gas and 13 inches water column for
propane. Manifold pressure under flow conditions is 3.5
inches water column for natural gas and 10 inches water
column for propane.

This fireplace is approved for bedroom and bed-sitting room
installation.

No external electricity (110 volts or 24 volts) is required
for the gas system operation. Expansion / contraction

noIses during heating up and cooling down cycles are
normal and are to be expected.

CARE OF GLASS, AND PLATED PARTS

Do not use abrasive cleaners to clean plated parts. Buff
lightly with a clean dry cloth. The GB20 is factory equipped
with 3/16" thick tempered glass. Use only replacement glass
available from your Napoleon dealer.

Do not substitute materials.

Clean the glass after the first 10 hours of operation with a
recommended gas fireplace glass cleaner. Thereafter
clean as required.

Do not clean glass when hot!

If the glass is not kept clean permanent discolouration
and / or blemishes may result.

Use only accessories designed for and

listed with your specific fireplace.

Provide adequate ventilation and combustion air.
Provide adequate accessibility clearance for serv­icing and operating the fireplace. Never obstruct
the front opening of the fireplace.

Objects placed in front of the fireplace must be
kept a minimum of 48" away from the front face of
the unit.

For safe and proper operation of the fireplace fol­low the venting & operating instructions exactly.

Provide a means for visually checking the vent
connection to the fireplace after the fireplace is
installed.

The fireplace must be installed against finished
walls. Do not install against a vapour barrier or
exposed insulation.

FIGURE 1

WS-415-137 / 05.15.00

VENTING

The GB20 is a vented appliance and must be connected to
a chimney in accordance with the current installation
codes. In absence of local codes, install to the current
National Fuel Gas Code, ANSI Z223.1, or the current
CAN/CGA B149, Installation Codes. This model can be
common-vented.

A minimum four inch diameter (4"ø) B-vent or class A vent
is required. Secure the B-vent to the exhaust collar on the
stove top with 3 screws. In cold climates, the use of a B­vent and an insulated chase is recommended.

VENT SAFETY SWITCH

This thermally activated switch, located in front of the draft
hood, senses an increase in temperature and acts as a
safety shut-off (A). It shuts down the gas to the main burner
in the event of a severe downdraft of air or a blocked or
disconnected chimney flue. If the flue is blocked or has no
"draw", the safety switch will automatically shut off the sup­ply of gas within 10 minutes.

Tampering with the safety switch can result in
carbon monoxide poisoning and possible death.

The one wire running from the vent safety switch is at­tached to terminal 1 of the valve (See 'B' below). The other
wire ( laying loose in the valve control area) may be at­tached to a wall switch or thermostat.

VENTING ACTION CHECK

A test for correct venting action must be made before
the installed unit can be left with the customer.

Follow the procedure below:

1. Close all doors and windows in the room / start ex-
haust fans in the home / turn the fireplace blower off (if so
equipped).

2. Set controls to "high" and light the unit.

3. Wait 5 minutes. Light a match and hold to the front of
the draft draft hood. FIGURE 4.

Venting action is satis­factory, if smoke and

flames are drawn into the
draft hood.

5

FIGURE 2

A

Venting action is unsatisfac­tory, if the smoke spills back,

and the flame splays out­ward. If venting action is un­satisfactory, turn off the unit,
wait 10 minutes and try again.
If the smoke is still not drawn
into the draft hood, turn the unit
off and check for vent block­age or restriction. If neces­sary, consult with a qualified
inspector. Until the draft prob­lem is corrected, the safety
switch will continue to cycle
the main burner on and off.

OPERATION / MAINTENANCE

OPERATING INSTRUCTIONS

When lit for the first time, the fireplace will emit a slight
odour for a few hours. This is a normal temporary condi­tion caused by the curing of the logs and the "burn-in" of
internal paints and lubricants used in the manufacturing
process and will not occur again.

FOR YOUR SAFETY READ BEFORE LIGHTING :

A. This fireplace is equipped with a pilot which must be lit

by hand while following these instructions exactly.

B. Before operating smell all around the fireplace area for

gas and next to the floor because some gas is heavier
than air and will settle on the floor.

C. Use only your hand to turn the gas control knob. Never

use tools. If the knob will not turn by hand, do not try to
repair it. Call a qualified service technician. Force or at­tempted repair may result in a fire or explosion.

D. Do not use this fireplace if any part has been under

water. Immediately call a qualified service technician to
inspect the fireplace and replace any part of the control
system and any gas control which has been under water.

LIGHTING INSTRUCTIONS
WARNING: The gas valve has an interlock device which

will not allow the pilot burner to be lit until the thermocou­ple has cooled. Allow approximately 60 seconds for the
thermocouple to cool.

When lighting and re-lighting, the gas knob cannot be turned
from pilot to off unless the knob is depressed slightly.

1. Stop! Read the above safety information on this label.

2. Turn off all electric power to the fireplace.

3. Turn the gas knob clockwise to off.

4. Wait five (5) minutes to clear out any gas. If you smell

gas including near the floor. Stop! Follow "B" in the above
safety information on this label. If you don't smell gas go
the next step.

After extended periods of non-operation such as following
a vacation or a warm weather season, the fireplace may
emit a slight odour for a few hours. This is caused by dust
particles in the heat exchanger burning off. In both cases,
open a window to sufficiently ventilate the room.

Purge all gas lines with the glass door of the fireplace
removed. Assure that a continuous gas flow is at the
burner before installing the door.

WHA T TO DO IF YOU SMELL GAS:

• Turn off all gas to the fireplace.

• Open windows.

• Do not try to light any appliance.

• Do not touch any electric switch; do

GAS KNOB

not use any phone in your building.

• Immediately call your gas supplier from a neighbour's
phone. Follow the gas supplier's instructions.

• If you cannot reach your gas supplier, call the fire de­partment.

CAUTION: Label all wires prior to disconnection when serv­icing controls. Wiring errors can cause improper and dan­gerous operation. Verify proper operation after servicing.
This fireplace and its venting system should be inspected
before use and at least annually by a qualified service per­son. The fireplace area must be kept clear and free of com­bustible materials, gasoline or other flammable vapours
and liquids. The flow of combustion and ventilation air must
not be obstructed.

1. In order to properly clean the burner and pilot assembly,
remove the logs to expose both assemblies.

2. Keep the control compartment, logs, burner, air shutter
opening and the area surrounding the logs clean by vacu­uming or brushing, at least once a year.

ADJUSTMENTS

3. Check to see that all burner ports are burning. Clean out
any of the ports which may not be burning or are not burn­ing properly.

4. Check to see that the pilot flame is large enough to
engulf the thermocouple and thermopile and reaches to­ward the burner with the third jet.

5. Replace the cleaned logs.

6. Check to see that the main burner ignites completely on

all openings when the gas knob for the burner is turned
on. A 5 to 10 second total light-up period is satisfactory. If
ignition takes longer, consult your Napoleon dealer / dis­tributor.

7. Check that the gasketing on the sides, top and bottom of
the door is not broken or missing. Replace if necessary.

VENTURI ADJUSTMENT

Both fireplace models have air shutters that have been
factory set open according to the chart below:

MODEL GB20

NG
LP

Closing the air shutter will cause a more yellow flame, but
can lead to carboning. Opening the air shutter will cause a
more blue flame, but can cause flame lifting from the burner
ports. The flame may not appear yellow immediately; al­low 15 to 30 minutes for the final flame colour to be estab­lished.

AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A

QUALIFIED GAS INSTALLER!

Gas piping is undersized. - turn on all gas appliances and see if pilot flame flutters, dimin-

ishes or extinguishes, especially when main burner ignites. Monitor
appliance supply working pressure.

- check if supply piping size is to code. Correct all undersized piping.

Unit is over-fired or under­fired.

- check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock­wise 2 or 3 turns and then placing pressure gauge tubing over the
