Thermo Pride MHA1-50N Installation And Service Manual page 12

All installations and services must be performed by qualified service personnel.
A plenum angles kit, (AOPS4942) is available for connecting the supply plenum
to the furnace. The kit consists of four angles that are to be screwed to into the
predrilled holes in the base of the furnace using # 8 screws.
The horizontal furnace installation should be on a service platform large enough
to allow for proper clearances on all sides and service access to the front of the
furnace (refer to Table 1). If the furnace is suspended, it must be supported at
both ends and in the middle with clearance allowed for removal of both access
doors. Line contact is only permissible between lines formed by the intersection
of the top and two sides of the furnaces casing and the building joists, studs, or
framing.
Equipment must be
installed in
accordance with
regulations of the
National Board of Fire
Underwriters and the
National Fuel Gas
Code. Authorities
having jurisdiction
should be consulted
before installations
are made.
