Answer 1

You did not give enough informaion about the item
1. what type of mobile home --year----model and make(brand)
----then you can try to contact the mobile home maker and find the furnace and manual

2 if you know the name of the furnace or the s/n --model ---year or band that would help you also.

3 the more information that you have the better chance you will have to locate the manual.
