S636. The special vent fittings, accessory concentric vent termination kits,
and accessory external drain trap have been certified to ULC S636 for use with
those Royal Pipe and IPEX PVC vent components which have been certified to
this standard. In Canada, the primer and cement must be of the same
manufacturer as the vent system – GVS-65 Primer (Purple) for Royal Pipe or
IPEX System 636, PVC/CPVC Primer, Purple Violet for Flue Gas Venting and
GVS-65 PVC Solvent Cement for Royal Pipe or IPEX System 636(1)t, PVC Cement
for Flue Gas Venting, rated Class IIA, 65 deg C. must be used with this
venting system – do not mix primers and cements from one manufacturer with a
vent system from a different manufacturer.
Follow the manufacturer’s instructions in the use of primer and cement and
never use primer or cement beyond its expiration date.
The safe operation, as defined by ULC S636, of the vent system is based on
following these installation instructions, the vent system manufacturer’s
installation instructions, and proper use of primer and cement. All fire stop
and roof flashing used with this system must be UL listed material.
Acceptability under Canadian standard CAN/CSA B149 is dependent upon full
compliance with all installation instructions.
Under this standard, it is recommended that the vent system be checked once a
year by qualified service personnel.

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.
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
gases 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.
Table 1 – Allowed Gas Furnaces
USE WITH:
35” Furnaces
(excluding Ultra Low NOx)
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:
External Condensate Drain Trap | 1 |
---|---|
Trap-Tee Vent Fitting (2-in./50mm PVC) | 1 |
Internal Drain Trap Plug | 1 |
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
gases 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.
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.
Fig. 8 shows the Trap Kit applied in Upflow applications for combustion-air
inlet piping. The Trap Kit may be applied only in vertically/up-flow
orientation. 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.
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.
AGACDKDTT01A: Installation Instructions
NOTE:
A. Maximum vertical distance from furnace exit to top of Vent Tee of 60-in.
(1.5M)
B. Provide enough vertical clearance to allow for 1/4-inch per foot (20mm per
meter) slope to termination
C. Maximum length of 36-in. (1 M); minimum length of 6-in. (150mm)
D. All vent or combustion air pipe must slope toward external condensate trap
and vent tee
E. Follow restrictions for Maximum Exposed Vent Length as stated in furnace
installation instructions
F. External Vent Trap MUST be protected from freezing
G. Flow of air may be either away from trap (vent side) or toward trap
(combustion air side)
H. When larger diameter pipe is used, a field supplied reducer is required
between the tee “G” and the drain trap “F”
NOTE: Some models not approved for downflow application.
AGACDKDTT01A: Installation Instructions
INSTALLATION
In this application, ALL vent piping MUST be sloped toward the External Vent
Trap Kit. The Internal Drain Trap Plug MUST be installed in the vent/high-
pressure side of the collector box trap connection in the furnace (see Fig.

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 when the trap kit is applied to the
vent/exhaust piping system. Failure to do this may result in vent gases being
released into the living space.
Failure to use a properly constructed 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.
CAUTION
UNIT OPERATION HAZARD
Failure to follow this caution could result in intermittent unit operation.
When the Internal Drain Trap Plug is used, the inducer housing may fill with
condensate if any of the vent piping that is external to the furnace is sloped
toward the furnace.
Example Trap Kit component installations are shown in Fig. 1. Install as shown
in Fig. 3 through Fig. 7.
NOTE: This kit is designed for use with 2-in. (50 mm) PVC/ABS DWV
vent/exhaust pipe applications. Additional pipe diameters are usable when
field-supplied PVC fittings are used with the condensate trap supplied in kit
(see Fig. 9) for proper placement of pipe diameter transitions.

Failure to follow this warning could result in personal injury, death or property damage.
Solvent cements and primers are combustible. Keep away from heat, sparks and open flame. Use only in well-ventilated areas. Avoid breathing in vapor or allowing contact with skin or eyes. -
Cement all vent and/or combustion-air inlet piping in place, per the instructions provided with the furnace.
Drainage System Layout and Installation
The furnace, indoor coil, and humidifier drains may be combined and drained
together. The indoor coil drain must have an external, field-supplied trap
prior to the furnace drain connection, and/or spill into an open stand pipe
(see Fig. 1 & Fig. 2). All drain connections (furnace, indoor coil, or
humidifier) must be terminated into an open or vented drain as close to the
respective equipment as possible to prevent siphoning of the other equipments’
drains. See equipment installation instructions for more information.
Outdoor draining of the furnace is permissible if allowed by local codes.
Use the accessory acid neutralizer kit as required by the application (to
protect shrubs, etc.), or as required by local codes.
CAUTION
PERSONAL INJURY OR PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in personal injury or property
damage.
Caution should be taken to prevent draining where slippery conditions may
cause personal injuries.
Excessive condensate drainage in open areas may cause saturated soil
conditions which may result in damage to plants and building foundations.
Condensate is not to be drained onto crawlspace floor from furnace or external
trap. Installations must comply with regulations of local building, heating,
plumbing, or other codes in effect in area where installation is made.
Complete the installation of the drainage system as follows:
- Dry fit the external condensate drain trap supplied with the kit into the vent trap-tee fitting. Apply field-supplied fittings as required if the 2-in. (50mm) trap-tee supplied with the kit was not used.
- Position the external condensate drain trap as required to match to the condensate drainage piping system.
- Dry fit remaining drainage system piping as shown in Fig. 1, Fig. 2 and Fig. 4 through Fig. 8, as appropriate for the specific installation requirements, using field-supplied components.
- IF ALLOWED BY LOCAL CODE, it is recommended that a short piece of clear tubing (6-in./0.2 M) be applied near the exit of each trap to allow observation of correct drain trap operation.
- Support all drainage system piping as needed, and in compliance with local codes.
- Verify that all drainage piping is sloped toward the open drain or condensate sump pump.
- Cement external condensate drain trap to the trap-tee and connection adapters, if any.
- Cement all remaining drainage system piping as required.
SYSTEM COMMISSIONING AND CHECKOUT
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 when the trap kit is applied to the
vent/exhaust piping system. Failure to do this may result in vent gases being
released into the living space.
Failure to use a properly constructed 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.
Follow these steps to verify proper operation of the trap and drainage system:
-
IF ALLOWED BY LOCAL CODE, it is recommended that a short piece of clear tubing (6-in./15 cm) be applied near the exit of each trap to allow observation of correct drain trap operation.
-
Prime the furnace internal condensate drainage trap per the furnace installation instructions. Collect or observe excess priming water at the end of the drainage piping system to verify that the trap is fully primed.
-
Prime the Trap Kit connected to the venting system by slowly pouring at least 32-oz. (1 liter) of water into the vent termination. Collect or observe excess priming water at the end of the drainage piping system to verify that the trap is fully primed.
-
Prime the Trap Kit connected to the combustion-air inlet piping system (IF USED) by slowly pouring at least 32-oz. (1 liter) of water into the combustion air inlet at the vent termination. Collect or observe excess priming water at the exit of the drainage piping system to verify that the trap is fully primed.
-
Once the furnace has been completely installed per the instructions supplied with the furnace, run the furnace for at least one hour to verify that all drainage systems are operating properly. Collect or observe condensate drainage at the exit of the drainage piping system to verify that the traps are fully primed and that the drain system is not blocked.
-
If the clear tubing has been applied to the drainage system, observe that EACH trap in the system is draining properly. NOTE that the combustion-air inlet piping system will likely NOT produce condensate.
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in personal injury or death.
If water vapor (fog) rather than liquid condensate is observed exiting the drain port any of the traps, that MAY be an indication that combustion gases are escaping through the drain system.
• RECHECK that all traps are properly water-primed.
• RECHECK that the Internal Drain Trap Plug is properly inserted into the internal condensate drain trap in the furnace (see Fig. 3).
• DO NOT operate the furnace until it is verified that all condensate drain traps are operating properly.
Failure to use a properly constructed 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. -
Listen for gurgling noises in the venting and drainage systems. This is an indication that there are dips in the piping system, or that the traps are not operating properly. Correct the conditions as needed.
CAUTION
UNIT OPERATION HAZARD
Failure to follow this caution could result in intermittent unit operation.
When the Internal Drain Trap Plug is used, the inducer housing may fill with condensate if any of the vent piping that is external to the furnace is sloped toward the furnace.
CAUTION
FIRE HAZARD
Failure to follow this warning could result in personal injury, death or property damage.
Solvent cements and primers are combustible. Keep away from heat, sparks and open flame. Use only in well-ventilated areas. Avoid breathing in vapor or allowing contact with skin or eyes. -
If there are water gurgling or sloshing sounds coming from the inducer housing, this is an indication that not all of the vent piping is sloped AWAY from the furnace and toward the Trap Kit. Correct the conditions as needed.
-
Shut down the furnace.
-
Once all drainage checks and verifications have been made, return the furnace to its normal operating condition.
-
Perform the venting system checklist as shown in the following WARNING box.
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the
venting system being placed into operation could result in carbon monoxide
poisoning or death.
The following steps shall be followed for each appliance connected to the
venting system being placed into operation, while all other appliances
connected to the venting system are not in operation:
- Seal any unused openings in venting system.
- Inspect the venting system for proper size and horizontal pitch, as required in the CSA B149.1 Natural Gas and Propane Installation Code and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies, which could cause an unsafe condition.
- As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building.
- Close fireplace dampers.
- Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they are operating at maximum speed. Do not operate a summer exhaust fan.
- Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the thermostat so appliance is operating continuously.
- Test for spillage from draft hood equipped appliances at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle.
