6.0 DUCTWORK
H10.0
Proper air
fl
ow is required for the correct operation of this furnace. Insuf
fi
cient air
fl
ow may cause erratic
operation, could cause the furnace to cycle on the high temperature limit, and may damage the heat
exchanger. Excessive air
fl
ow may result in an excessively noisy duct system and may result in undesirable
consequences such as creating uncomfortable drafts.
If air conditioning is to be used with the furnace, the duct system must be capable of delivering the correct
amount of air
fl
ow for each system.
The ductwork should be sized and constructed in accordance with accepted industry standards. Duct sizing
and construction information may be obtained from:
•
A.C.C.A. (Air Conditioning Contractors of America)
•
A.S.H.R.A.E. (American Society of Heating, Refrigeration and Air Conditioning Engineers)
•
H.R.A.I. (Heating, Refrigerating and Air Conditioning Institute (Canada)
•
S.M.A.C.N.A. (Sheet Metal and Air Conditioning Contractors’ National Association (United States)
All of the above professional organizations have duct sizing manuals available.
The total static pressure drop of the air distribution system (including
fi
lters) should not exceed 1.0” w.c.
H3.8
DO NOT ALLOW GAS PIPING TO BE ROUTED THROUGH JOIST SPACES THAT ARE
USED FOR RETURN AIR PURPOSES. DO NOT USE JOIST SPACES FOR RETURN AIR
PURPOSES IF THE JOIST SPACE ALREADY CONTAINS PLUMBING STACKS, CHIMNEY
COMPONENTS, ETC. UNLESS THE PORTION USED FOR RETURN AIR PURPOSES CAN
BE COMPLETELY ISOLATED FROM PORTIONS WITH OTHER USAGES.
NEVER ALLOW THE PRODUCTS OF COMBUSTION FROM THE FLUE TO ENTER THE
RETURN AIR OR SUPPLY AIR DUCTWORK.
ALL RETURN AIR DUCTWORK MUST BE ADEQUATELY SEALED AND SECURED TO
THE FURNACE WITH SHEET METAL SCREWS. TAPE THE SHEET METAL SEAMS IN THE
VICINITY OF THE FURNACE WITH DUCT TAPE OR SIMILAR MATERIAL.
WHEN THE FURNACE IS MOUNTED ON A PLATFORM WITH RETURN AIR THROUGH THE
BOTTOM, IT MUST BE SEALED AIR TIGHT BETWEEN THE FURNACE AND THE RETURN
AIR PLENUM. THE FLOOR OR PLATFORM MUST PROVIDE SOUND PHYSICAL SUPPORT
OF THE FURNACE WITHOUT SAGGING OR GAPS AROUND THE BASE. IT MUST ALSO
BE SEALED BETWEEN THE SUPPORT AND THE BASE.
FAILURE TO PREVENT PRODUCTS OF COMBUSTION FROM BEING CIRCULATED INTO
THE LIVING SPACE CAN CREATE POTENTIALLY HAZARDOUS CONDITIONS, INCLUDING
CARBON MONOXIDE POISONING THAT COULD RESULT IN PERSONAL INJURY OR
DEATH.
