A fused disconnect switch should be field provided for the unit.

The switch must be separate from all other circuits. Wire entry

at knockout openings require conduit fittings to comply with

NEC and/or local codes. Refer to Figure 10 for installation

location. If any of the wire supplied with the unit must be

replaced, replacement wire must be of the type shown on the

wiring diagram and the same minimum gauge as the replaced

wire.

Electrical line must be sized properly to carry the load. Each

unit must be wired with a separate branch circuit fed directly

from the meter panel and properly fused.

CAUTION: When connecting electrical power and control

wiring to the unit, waterproof type connectors

MUST BE USED so that water or moisture cannot

be drawn into the unit during normal operation. The

above waterproofing conditions will also apply

when installing a field-supplied disconnect switch.

Refer to Figure 5 for typical field wiring and to the appropriate

unit wiring diagram for control circuit and power wiring

information.

COMBUSTION DISCHARGE

The products of combustion are discharged horizontally

through two screened (hooded) openings on the upper gas

heat access panel.

GAS PIPING

Proper sizing of gas piping depends on the cubic feet per hour

of gas flow required, specific gravity of the gas and the length

of run. “National Fuel Gas Code” Z223.1 should be followed in

all cases unless superseded by local codes or gas utility

requirements. Refer to Table 5.

The heating value of the gas may differ with locality. The value

should be checked with the local gas utility.

NOTE: There may be a local gas utility requirement specifying

a minimum diameter for gas piping. All units require a

1 inch pipe connection at the entrance fitting.

MBH rating should be reduced at the rate of 4 percent for each 1,000 feet above 4,500 feet.

Based on maximum input and 1075 Btu/Ft

The air flow must be adjusted to obtain a temperature rise within the range shown.
