NEVER ALLOW THE PRODUCTS OF COMBUSTION TO ENTER THE RETURN DUCTWORK OR
CIRCULATING AIR SUPPLY. ALL RETURN DUCTS MUST BE ADEQUATELY SECURED TO THE
FURNACE AND COMPLETELY SEALED. ALL OTHER DUCTWORK MUST BE SECURED WITH
APPROVED CONNECTIONS AND SEALED AIRTIGHT. THE VENT AND COMBUSTION AIR SUPPLY
PIPES MUST BE PROPERLY INSTALLED AND SUPPORTED TO PREVENT LEAKAGE AS NOTED
ELSEWHERE IN THESE INSTRUCTIONS. WHEN A FURNACE IS MOUNTED ON A PLATFORM IT MUST
BE SEALED AIRTIGHT BETWEEN THE FURNACE AND RETURN DUCTWORK. THE FLOOR OR
PLATFORM MUST PROVIDE SOUND PHYSICAL SUPPORT FOR THE FURNACE WITHOUT
CRACKING, GAPS, SAGGING ETC. AROUND THE BASE AS TO PROVIDE A SEAL BETWEEN THE
SUPPORT AND THE BASE. FAILURE TO PREVENT PRODUCTS OF COMBUSTION FROM ENTERING
THE RETURN AIR SUPPLY MAY CAUSE SEVERE ILLNESS OR DEATH FROM CARBON MONOXIDE
POISONING.
Install the return air to terminate through the base under the furnace. For installations where return air
ducts cannot be run under the floor, the return air supply may be taken from the side(s). The solid
bottom supplied on the furnace must remain in place.
WHERE THE MAXIMUM REQUIRED AIR FLOW IS 1800 CFM OR GREATER THE BOTTOM OR
BOTH SIDES MUST BE UTILIZED FOR RETURN AIR SUPPLY. NEVER USE THE REAR OF THE
FURNACE FOR THE RETURN CONNECTION.
A SOLID METAL BASEPLATE IS SUPPLIED WITH THIS FURNACE. THIS BASEPLATE MUST BE
IN PLACE WHEN THE FURNACE IS INSTALLED WITH SIDE(S) RETURN AIR DUCTS. FAILURE
TO DO SO MAY PERMIT COMBUSTION PRODUCTS TO ENTER THE LIVING SPACE. THIS MAY
CREATE POTENTIALLY HAZARDOUS CONDITIONS SUCH AS CARBON MONOXIDE
POISONING OR DEATH.
