relié à l’installation conforme aux instructions ci- haut mentionnées. Le
standard Canadien recommande l’ inspection par un personel qualifié et
ce, une fois par année.
Les autoritées ayant juridiction (inspecteurs de gas, inspecteurs en
bâtiments, département des incendies, etc) devraient être consultées
avant l’installation afin de déterminer si un permis est requis.
INTRODUCTION
This instruction covers the installation of the External Vent Trap Kit with
the furnaces listed in Table 1. This kit may be applied to either or both
the vent/exhaust piping system and/or the combustion-air inlet piping
system.
Very high efficiency gas furnaces tend to condense nearly all of the
water vapor products of combustion within the furnace. Since there is
less water vapor to condense in the venting system, extra care must be
given to verifying that the drain trap(s) will self-prime under normal
conditions. IT IS IMPERATIVE that these instructions be followed fully
to ensure proper operation of the venting drainage system.
Table 1 – Allowed Gas Furnaces
DESCRIPTION AND USAGE
Use this External Vent Trap Kit (“Trap Kit”) to allow the furnace venting
system to be positioned below the level of the furnace. In this
configuration, the condensate from the venting system does NOT drain
to the furnace (see Table 1 ).
This Trap Kit may also be used for the combustion air inlet piping, either
by itself, or in conjunction with the Trap Kit being applied to the
vent/exhaust piping. When used for the combustion air inlet piping, only,
the venting system must be installed as shown in the furnace installation
instructions.
This External Vent Trap Kit (“Trap Kit”) contains the following items:
Application to Vent/Exhaust Piping Systems
The venting system is configured such that ALL of the venting system is
sloped toward the Trap Kit, and therefore, all of the vent system
condensate is directed to the Trap Kit. The Internal Drain Trap Plug
MUST BE APPLIED to the vent side of the collector box trap
connection of the furnace to prevent vent gasses from being introduced
into the drainage system, and possibly the living space. See Fig. 3 .
Application to Combustion Air Inlet Piping
Systems
This Trap Kit may used to help prevent liquid moisture from the inlet
piping system from entering the furnace. The Trap Kit may be used on
the inlet piping side, even if a Trap Kit is not used on the venting side
(see Fig. 1 , Fig. 2 and Fig. 8 ) and the Furnace installation instructions
for more information on the application of the Trap Kit on
combustion-air inlet piping systems.
Fig. 8 shows the Trap Kit applied in upflow applications for
combustion-air inlet piping. The Trap Kit may be applied in any furnace
orientation-upflow, downflow, horizontal. The Trap Kit should be
located as close as possible to the furnace. If the Trap Kit is applied
ONLY to the combustion air inlet piping system, the vent/exhaust piping
should be configured as shown in the furnace installation instructions,
NOT these instructions.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in personal injury or
death.
The Internal Drain Trap Plug MUST BE APPLIED to the vent side of
the collector box trap connection of the furnace. Failure to do this may
result in vent gasses being released into the living space.
Failure to use a properly constructed trap(s), applying the incorrect
trap(s), or NOT water-priming trap(s) before operating furnace may
allow positive pressure vent gases to enter the structure through drain
tube. Vent gases contain carbon monoxide which is tasteless and
odorless.
USE WITH:
35” Furnaces
(excluding Ultra Low NOx)
External Condensate Drain Trap 1
Trap-Tee Vent Fitting (2-in./50mm PVC) 1
Internal Drain Trap Plug 1
NOTICE
!
OPTIONAL CONFIGURATION FOR COMBUSTION
AIR INLET PIPE
In applications where there is a risk of excessive moisture entering the
combustion air inlet pipe, a moisture trap may be added to the inlet pipe
to help prevent moisture from entering the furnace from the combustion
air inlet pipe.
When sizing venting systems, the equivalent length of the optional inlet
pipe moisture trap must be taken into account.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution could result in intermittent unit operation.
When used, install the Trap Kit at the lowest point of the
combustion-air inlet piping system, within 24–in. (0.6 M) of the
furnace. This will help prevent water build-up in the combustion-air
inlet piping, and help prevent erratic unit operation.
