CAUTION: Use copper or copper-dad aluiai-
num conductors only. Use a separate branch
electrical circuit for this furnace.

A disconnect

ing means must be located within sight of, and
readily accessible to, the furnace.

See Fig. 2 for wiring diagram showing the proper

field high- and low-voltage wiring. Make all elec
trical connections in accordance with the National

Electrical Code and any local codes or ordinances

that might apply.

WARNING: The unit cabinet m.ust have an

uninterrupted or unbroken electrical ground to

minimize personal injury if an electrical fanlt

should occur. This may consist of electrical
wire or approved conduit when installed in
accordance with e.Kisting electrical codes.

exposed to cold air infiltration, drafts from win
dows, doors, or other openings leading to the out

side, or exposure to air currents from warm or cold
air registers; or to exposure where the natural circu
lation of the air is cut off — such as behind doors,
above or below mantels, shelves, etc.

The thermostat should not be exposed to heat

from nearby fireplaces, radios, televisions, lamps,

or rays from the sun. Nor should the thermostat be
mounted on a wall containing pipes or warm air
ducts, or a flue or vent that could affect its
operation and prevent it from properly controlling
the room temperature. Any hole in the plaster or
panel thru which the wires pass from the
thermostat should be adequately sealed with suit
able material to prevent drafts from affecting the

thermostat.

LOW-VOLTAGE WIRING — Make field low-

voltage connections at the low-voltage terminal
strip. See Fig. 2.

Set the thermostat heat anticipator at the

settings indicated below. If additional controls are
connected in the thermostat circuit, their amp draw
must be added to this setting. Failure to make the
setting will result in improper operation of the
thermostat.

58GS050 thru 150 sizes with

BDP 646AW gas valve.
Heat/Cool or Heat only models................ 0.55 amp

58GS175 size with Essex 242NS gas valve,

Heat/Cool models.......................................0.65 amp

With addition of automatic vent damper, antici
pator setting should be 0.12 amp.

The room thermostat should be located where it

will be in the natural circulating path of room air.
Avoid locations where the thermostat would be
