Furnace

[Peppers]

Our furnace in our new travel trailer doesn't blow much air out. This is a high output furnace and we wonder if it is because a lot of the heat is blown into the under belly?

Need to check that ducting is properly attached to furnace discharge plenum

Then need to check air flow at each register.
Find any that are low/lacking air flow...then you need to check for obstruction in duct. Could be clogged, crushed or to tight of a bend in duct.

Short of sticking a camera down thru duct.......you can disconnect duct at furnace and then use blower (wet/dry vac hose connected vac discharge, leaf blower etc.) to blow air thru duct and check air flow coming out register.
High air flow in....low/lacking air flow out......problem with duct.

New TT..........warranty issue

When we first picked up our new coach two of the four heat ducts had fallen off at the furnace. This let all the heat blow out onto the closet and drawer area. Floor near them was hot as could be. Front of coach ice cold.

my keystone is the same way. it does keep the TT warm though.

Does the burner cycle while heating? If the flame cycles you probably have a restriction in the warm air distribution.

Did you look at the filter if it has one? Could be the wrong one. We have one that heats at 4 degrees outside and keeps you warm as toast.
