Horizontal Units - Rheem RGPH Installation Instructions Manual

GAPS, ETC., AROUND THE BASE AS
TO PROVIDE A SEAL BETWEEN
THE SUPPORT AND THE BASE.
FAILURE TO PREVENT PRODUCTS
OF COMBUSTION FROM BEING
CIRCULATED INTO THE LIVING
SPACE CAN CREATE POTENTIALLY
HAZARDOUS CONDITIONS,
INCLUDING CARBON MONOXIDE
POISONING THAT COULD RESULT
IN PERSONAL INJURY OR DEATH.
DO NOT, UNDER ANY
CIRCUMSTANCES, CONNECT
RETURN OR SUPPLY DUCTWORK
TO OR FROM ANY OTHER HEAT
PRODUCING DEVICE SUCH AS A
FIREPLACE INSERT, STOVE, ETC.
DOING SO MAY RESULT IN FIRE,
CARBON MONOXIDE POISONING,
EXPLOSION, PERSONAL INJURY
OR PROPERTY DAMAGE.
WARNING
!
BLOWER AND BURNERS MUST
NEVER BE OPERATED WITHOUT
THE BLOWER DOOR IN PLACE.
THIS IS TO PREVENT DRAWING
GAS FUMES (WHICH COULD
CONTAIN HAZARDOUS CARBON
MONOXIDE) INTO THE HOME THAT
COULD RESULT IN PERSONAL
INJURY OR DEATH.
UPFLOW UNITS
1. Position the unit to minimize long
runs or runs with many turns and
elbows.
2. Open the return air compartment.
a. If using side or back return air,
install the bottom base.
WARNING
!
A SOLID METAL BASE PLATE, SEE
TABLE 1, OR FURNACE
CLEARANCE LABEL FOR PART
NUMBER MUST BE IN PLACE
WHEN THE FURNACE IS
INSTALLED WITH SIDE OR REAR
AIR RETURN DUCTS. FAILURE TO
INSTALL A BASE PLATE COULD
CAUSE PRODUCTS OF
COMBUSTION TO BE CIRCULATED
INTO THE LIVING SPACE AND
CREATE POTENTIALLY
HAZARDOUS CONDITIONS,
INCLUDING CARBON MONOXIDE
POISONING OR DEATH.
b. Cut an opening in the side or
back. The opening should be cut
the full width of the knockouts on
the unit.
NOTE: Where the maxiumum air flow
is 1800 CFM or more, both sides or the
bottom must be used for return air.
3. Connect the return duct or return air
cabinet to the unit. Make the
connection air tight to prevent
entraining combustion gases from
an adjacent fuel-burning appliance.
4. Be sure to have adequate space
for the unit filter.
NOTE: DO NOT take return air from
bathrooms, kitchens, furnace rooms,
garages, utility or laundry rooms, or
cold areas.
5. If summer air conditioning is desired,
position the indoor coil on the top of
the unit. Insure that no air can
bypass this coil.
6. Connect the supply air plenum to the
furnace plenum opening.
DOWNFLOW UNITS
1. Position the unit to minimize long
runs or runs with many turns and
elbows.
2. If summer air conditioning is desired,
position the indoor coil on the
bottom of the unit. Insure that no air
can bypass this coil.
3. If installing on a combustible floor
and not using an air conditioning
plenum, install the special
combustible floor base. See Figure 4.
WARNING
!
THE DOWNFLOW FURNACE
DESIGN IS CERTIFIED FOR
INSTALLATION ON A NON-
COMBUSTIBLE FLOOR. USE THE
SPECIAL BASE SPECIFIED ON THE
FURNACE CLEARANCE LABEL.
FAILURE TO INSTALL THE SPECIAL
BASE MAY RESULT IN FIRE,
PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH. THIS SPECIAL
FIGURE 5
COMBUSTIBLE FLOOR BASE
BASE IS SHIPPED FROM THE
FACTORY AS AN ACCESSORY.
4. Connect the furnace to the supply
air plenum.
5. Connect the return air ducting to the
return air opening at the top of the
unit. Make the connection air tight to
prevent entraining combustion
gases from an adjacent fuel-burning
appliance.
6. Be sure to have adequate space
for the unit filter.
NOTE: DO NOT take return air from
bathrooms, kitchens, furnace rooms,
garages, utility or laundry rooms, or
cold areas.

HORIZONTAL UNITS

1. Position the unit to minimize long
runs or runs with many turns and
elbows.
2. If summer air conditioning is desired,
position the indoor coil on the supply
air side of the unit. Insure that no air
can bypass this coil.
3. Connect the furnace to the supply
air plenum.
4. Secure the four angle brackets
shipped with the unit to the return air
opening. See Figure 6. Connect the
return air ducting to the return air
opening at the top of the unit. Make
the connection air tight to prevent
entraining combustion gases from
an adjacent fuel-burning appliance.
5. Be sure to have adequate space
for the unit filter.
NOTE: DO NOT take return air from
bathrooms, kitchens, furnace rooms,
garages, utility or laundry rooms, or
cold areas.
