syncFURNACE OD Instruction & Installation Manual – Rev 09 Pg. 17 of 81
GENERAL VENTING:
syncFURNACE OD utilizes a modulating gas power burner and incorporates a sealed combustion venting
design. This product requires a “Special Venting System” designed for pressurized venting.
syncFURNACE OD is suitable for use for sidewall (horizontal) and vertical venting using field supplied
venting materials. This product is approved for both direct vent (sealed combustion) and direct exhaust
(sealed exhaust, room dependent combustion air supply) in both horizontal and vertical installation
configurations.
This product must be installed so that all air for combustion is taken from the outside atmosphere and all
combustion flue gas is discharged safely to the outside atmosphere.
Pay careful attention to the following:
1. DO NOT common vent syncFURNACE OD with any other new and/or existing gas fired product.
2. It is highly recommended that syncFURNACE OD be located so that venting lengths can be as short
and direct as possible. Pay special attention to manage the impact of the steam plume of the
exhaust gas to minimize the impact to surrounding structures.
3. Inspect all finished exhaust vent/air intake piping to ensure:
a. All piping and fittings used are marked and made of approved material(s).
b. Meets the acceptable size, length and number of elbow requirements listed in this manual.
c. Installation is in accordance with prevailing provisions of local codes.
d. Installation meets the requirements of this instruction as well as the instructions of the field
supplied venting material(s) and/or product(s).
4. Venting, condensate drainage and combustion air must be installed in compliance with local codes
and must follow the instructions provided with components and/or systems. All venting must be
installed in accordance with the requirements of the jurisdiction having authority:
a. In Canada, Part 8, Venting Systems of the CAN/CGA B149.1 or B149.2 Code and any other
local building codes are to be followed.
b. In the U.S., Part 7, Venting of Equipment of the National Fuel Gas Code, ANSI 223.1, latest
edition, prevails.
c. Where there is a discrepancy between the installation instructions below, and the code
requirements, the more stringent shall apply.
5. DO NOT install vent pipe such that flue gases flow downwards. MUST be vented vertically
upwards or horizontal with upward slope – see below requirements for acceptable slopes.
6. Inspect finished vent system thoroughly to ensure all joints are airtight and comply with these
instructions and the instructions provided by the field supplied venting materials.
7. It is highly recommended that annually the entire vent system be inspected for leaks.
8. Keep exhaust gas plumes well away from all building air intakes, including those located on
neighboring structures. It is the installer’s responsibility to ensure proper installation that prevents
damage from exhaust gas plumes to exterior walls and neighboring structures.
9. Side-wall vent terminations should be located on a wall that is least likely to receive high-speed,
prevailing winds. High-speed, prevailing winds may affect water heater operation and could cause
flue gas plumes damage to occur to nearby exterior walls. It is the installer’s responsibility to
review the side-wall terminations and take all precautions necessary to shield and protect the vent
terminations and exterior walls from damage.
10. It is the responsibility of the installer to contact local building or fire officials concerning any
installation restrictions and/or inspection requirements that may apply. Permits may be required
before initiating installation.
11. Installation in manufactured (mobile) homes shall conform to the Manufactured Home Construction
and Safety Standard, Title 24 CFR, Part 3280 and/or CAN/CSA Z240 MH Series, Mobile Home.
