equipment.
7. Ensure the draft, when fi ring, is negative and constant. A reading of -0.02
to -0.04”wc (-0.508 to -1.016 mm) when the unit and stack are cold usually
indicates suffi
cient draft. When the unit is running and the stack is hot, the
draft should read -0.04 to -0.08 “wc (-1.016 to -1.524 mm) negative.
8. The installation of a draft regulator by the client/contractor is
recommended at all installations. This will help to maintain the required
draft. The placement of the draft regulator should be as shown in Figure 3.
Insulate the section of the chimney duct within the building.
9. Concentration levels of only a few ppm of chlorine containing compounds
in combustion air can produce serious corrosion of the fl ue over long
periods of time. High chlorine containing compounds such as carbon
tetrachloride or perchloroethylene would be prime suspects.
 Exhaust Side Wall Venting
Boilers for which sidewall venting (Figure 4) may be utilized are propane, natural
gas, or combination propane and natural gas sizes 10 to 30 HP.
Adhere to the following for installations requiring sidewall venting:
10. Flue vent piping must be pitched upward at ¼ in (6.35 mm) per one foot
(3.048 m) of length.
11. An UL-approved draft fan must be installed to provide suffi cient draft (-0.02
to -0.04” wc) to safely vent products of combustion.
12. The draft fan should be located as close to the fl ue outlet as possible.
13. Draft regulation suffi cient to lower the draft to between -0.02 to -0.04 “ wc
may be required. The draft regulator must be between the boiler and the
fan.
14. The draft fan shall have an air fl ow proving switch wired in series with the
boiler air safety switch.
15. The sidewall vent total length from boiler exhaust to termination shall not
exceed 35 feet (10.6 m) with 4 elbows maximum.
Testing
Upon completion of the installation, perform the following testing:
1. A pneumatic test of water piping not exceeding 15 psig.
2. Leak tests at all welds and joints to ensure that the system is free from
leaks.

CAUTION
Boilers damaged due to adverse water
conditions are not covered by warranty.
The weight of all piping must be
properly supported. Failure to support
piping may result in equipment
damage and/or system leakage.
Piping must take into consideration
potential for freezing interference and/
or damage as a result of expansion,
contraction, vibration, or other
movements.
Dirt, water, and/or other debris in the
piping system after welding may result
in equipment failure.
To maintain a reasonable
temperature in the equipment area
and ensure safety to personnel, the
section of the chimney duct within
the building should be insulated.
