Where is access to furnace in 1997 Allegro Bus?

[jstoren11]

We turned on the heat the other night and successfully got heat in the front and back areas. Last night, the back heated just fine but the front only blew cold air. We can't find out how to access the furnace in this unit. We have the owner's manual for the freightliner chassis but not for the coach. The front furnace is located underneath the cabinet behind the passenger seat. We just can't find any way to access it.

Thanks,

I don't have an Allegro but my furnace is accessed from the outside. Look for a vent and panel.

Well, it's blowing hot air now, don't know why. We have access to one side of the furnace (the motor side of the furnace) from the outside of the motorhome but my husband doesn't know how to get the heater out to check the flame or clean it, as instructed in the furnace manual. According to the manual, there is a window that you are supposed to be able to look at to see the flame. It's called a burner observation window. We don't see it or can't get to it. Model of this furnace is Suburban SF35.

Forgive my translation of what my husband needs! Anybody with this motorhome that knows how to get the heater out?

Thanks,

Here's the manual (which you may already have):

REMOVAL SECTION is near end of manual and it looks like there is an access panel inside the RV that is opposite the 2 vents that are outside.

Husband removed one screw and pulled it out, just like in this video.

Tiffin typically installs an air intake grill with wooden louvers directly in front of the furnace. Look for the grill, pop out the wooden buttons that cover the screw heads, and remove the grill to gain access to the furnace from inside the coach.
