A - Return Air Transition installation.

Refer to figure 2,

1 - Lay GHR26 unit on its back (exposed internal parts facing up), (Figure 2 shows installed position.)

2 - Remove the three rear-most cabinet screws at return air inlet (3 each side),

3 - Cut two strips from roll of adhesive-backed foam tape (provided) to fit two cabinet sides as shown in figure. Apply to cabinet sides.

4 - Install transition as shown.

5-Install filter as shown in GHR26 installation instructions. GHR26Q4!5-100 unit will accept installation of GSR14Q4/5-80!100 unit filter. GHR26-50 and -75 units require a field provided 14x25x1 filter.

B - Supply Air Transition Installation.

Refer to figure 2.

t - Remove the three rear-most cabinet screws at supply air inlet (3 each side).

2 - Cut two strips from roll of adhesive-backedfoam tape (provided) to fit two cabinet sides as shown in figure. Apply to cabinet sides.

3 - Install transition as shown. C - Base Rails Installation,

Refer to figure 2

1 - Install base rails as shown in figure 2. D - Unit Installation

1 - Align unit with existing supply air plenum (coil

cabinet in air conditioning applications) and return air plenum, Make connections to unit.

2- Connect low voltage wiring as illustrated in GHR26 installation instructions.

3-Connect high voltage wiring as outlined in GHR26 installation instructions.

4-Connect gas piping as outlined in GHR26 installation instructions.

Consult local codes for flexible connector installation restrictions on GHR26 furnace.

5- Connect venting as outlined in GHR26 installation instructions,

Note - Mufflers can not be used in GHR26 installation. Check existing venting for size (diameter and length). It should meet the specifications as outlined in GHR26 installation instructions. If a concentric vent is used for GHR26-100 unit, it must be identified as catalog number 33K97.

6 - Connect heat exchanger condensate drain line as outlined in GHR26 unit installation instructions.

Note - Coil drain line must not be connected to

heat exchanger condensate drain line. ff lines were connected, debris from evaporator could affect heat exchanger operation.

7 - Continue with Unit Start-up Section as outlined in GHR26 installation instructions,
