90 plus for manufactured home

i own a manufactured home built in 93 with original coleman. would like to upgrade to a 90 plus, can i put a regular furnace in or does code only allow one specifically designed for mobile home? if so who makes a 90 plus for trailers? I understand it has to be a down draft setup. well after some searching I see that miller and coleman both sell 90 plus furnaces for manufactured homes with energystar ratings. what I,ve learned is the type of vents used and how the cold air returns r set up u have to use mobile home specific hvac.

Most manufactured housing is designed with a higher static pressure than conventional housing. With that being said, there really is nothing physical (besides space) keeping you from using conventional equipment. BUT!!!! I can guarantee you that your insurance company has a big problem with it, and who needs that?

Stick with the designed and certified units. The Intertherm M3RL 90+ group of units has the same footprint as the Coleman/Evcon older 80% units, so it can fit in the same closet area as the older units. The Coleman 90% products are larger and oftentimes presents installation problems.
Settle down! If you were that important, the city would give you lights and a siren for your car

Check out mobilehomerepair.com. Great site for all mobile home questions and lots of experience with HVAC for mobile/manufactured homes. No, I'm not pimping for the site.
