We created a separate and distinct category for mobile home equipment because of the unique demands placed on cooling and heating systems used in these applications. The primary difference between a mobile home furnace and a furnace designed for a site-built home is the way the furnace is ducted, vented, and installed.
The ducting in a mobile home is smaller and therefore more restrictive, so the furnace blower must be designed to overcome the greater resistance to airflow. This ensures proper air delivery from each supply register. Standard furnaces will not provide the rated air delivery in a mobile home application.
Your new mobile home furnace also uses a venting design known as sealed combustion which safely draws combustion air from outside to minimize noise and drafts.
Finally, the return air is drawn through a louvered grill on the front of the furnace, without the need for return ducting. The return air on a standard furnace is drawn from the top (or bottom) and must be ducted to a remote location.
Standard furnaces from almost all other manufacturers are not designed or rated for use in mobile homes and can be unsafe if an attempt is made to use them improperly. All furnaces and equipment in this category are design-specific for use in mobile and manufactured homes.
Air Conditioning ready
The Coleman DGAH series gas furnaces are air conditioning ready and can serve as the indoor blower section for up to four tons of cooling. (An optional five-ton blower is available).
Simply add the Coleman evaporator cooling coil into the furnace cabinet and an outdoor air conditioning condenser and you will have a complete home comfort system.
The heart of the system is a long-life, tubular heat exchanger. Many heat exchangers are designed using a highly stressed, deep-drawn drum construction.
The Coleman furnace features a corrosion-resistant, aluminized steel, wraparound exchanger with round-corner construction for excellent stress resistance and superior heat distribution.
Propane and natural gas ready
Conversion to propane gas is fast and easy. All models are provided with a convertible gas valve and gas orifices for both natural and propane gas.
The Coleman 80% efficient mobile home gas furnace features a designer appearance that will look and feel right in your home. The sculptured door and contoured corners help enhance any decor. Behind the appealing exterior design this Coleman furnace starts with a proven sealed-combustion, down flow (ductwork under the floor) supply air design. Sealed-combustion safely draws combustion air from outside to minimize noise and drafts while increasing operating efficiency.
