Specifications

3.2.2 Indoor and Outdoor Shelter
Installations
Vent pipe diameter must be as required by the
National fuel Gas Code Z223.1 or the Canadian
Installation Codes for Gas Appliances CAN/CSA-
B149.1. Undersized pipe can result in inadequate
venting and oversize pipe can result in vent
condensation. In either case the result can be
release of combustion products to the indoors.
This can cause serious injury or death by carbon
monoxide poisoning or asphyxiation.
WARNING
Le diamètre des tuyaux de ventilation doit
répondre aux exigences du National Fuel Gas
Code Z223.1 ou du code canadien des installa-
tions des appareils à gaz CAN/CSA B149.1. Des
tuyaux trop petits risquent d’entraîner une ventila-
tion inadéquate et des tuyaux trop gros risquent
de provoquer une condensation dans les tuyaux.
Dans un cas comme dans l’autre, des produits
de combustion risquent de s’échapper dans
le bâtiment et causer des blessures graves ou
l’asphyxie par le monoxyde de carbone.
AVERTISSEMENT
All indoor installations and outdoor shelter
installations require a factory approved draft hood. The
draft hood must be installed without modication. All
vent installations must be made in accordance with all
local, state or provincial codes and with:
1. The National Fuel Gas Code, ANSI
®
Z223.1
(NFPA
®
54), latest edition; pay particular attention
to the chapter addressing "Venting of Equipment".
Applicable provisions of additional applicable
local building codes may also need to be followed.
2. In Canada, CAN/CSA B149.1.
Avoid long horizontal runs of the vent pipe, and
90° elbows, reductions and restrictions. Horizontal runs
should have at least a 1/4 inch rise per foot (20mm per
meter) in the direction of ow.
Avoid terminating heater vents near air
conditioning or air supply fans. The fans can pick up
exhaust ue products from the heater and return them
inside the building, creating a possible health hazard.
Do not locate the vent terminal where ue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air ow to
and from vent terminal. Do not terminate the vent under
decks, stairways, or car ports.
Be sure to support all venting so that connections
will not separate and so that the weight of the vent pipe
does not rest on the heater draft hood. All connections
NOTE Except for the combustion air openings
requirements, in Canada, follow Canadian
Standard, CAN/CSA-B149.1 or local codes.
Follow the requirements of Table 3 for the
minimum combustion air openings required.
Exhaust Fans or Vents: Any equipment which
exhausts air from the room where the heater is installed
can deplete the combustion air supply or reverse
the natural draft action of the venting system. This
could cause ue products to accumulate in the room.
Additional air must be supplied to compensate for such
exhaust.
The information in Table 3 is not applicable in
installations where exhaust fans or blowers of any
type are used. Such installations must be designed by
qualied engineers.
The heater must be completely isolated and
protected from any source of corrosive chemical fumes
such as those emitted by trichlorethylene, perchloro-
ethylene, chlorine, etc.
Do not store any chemicals, cleaners, or other
corrosive material near combustion air openings
or in the room. Avoid locating appliance vents in
the vicinity of combustion air openings. Failure
to prevent corrosive materials from mixing with
combustion air can result in reduced heater life
and unsafe heater operation.
WARNING
Ne pas entreposer ni utiliser d'essence ni d'autres
vapeurs ou liquides inammables à proximité de
cet appareil ou de tout autre appareil.
AVERTISSEMENT
3.2 Vent Pipe Sizing and General
Installation
3.2.1 Outdoor Installations
For outdoor installations, exhaust venting
considerations will determine the placement of the
heater, see Section 2.3.4. If the heater cannot be placed
so as to meet the requirements stated in Section 2.3.4, a
vent pipe and cap may be added to the heater to move
the exhaust vent opening to a position that complies
with the requirements.
When the heater is installed in areas of high
wind or when unavoidably installed near a vertical
obstruction where downdrafting may occur, it may be
desirable to add a vent cap directly to the top of the
heater.
In all cases, vent pipes and caps must be of the
same diameter as the exhaust outlet of the heater.
Approved vent caps may be obtained through your
Zodiac distributor.
