3. Allow 5 minutes for pilot to establish a draft before

operating furnace.

4. To operate furnace, follow procedures on lighting instruc-

tion label attached to furnace.

5. With furnace operating, set thermostat below room tem-

perature and observe that furnace goes off. Set thermostat
above room temperature and observe that furnace restarts.

Adjustments

1. Set gas input rate.

There are 2 methods of adjusting the gas input rate. The
preferred method is by using Table 6 and following
instructions in item a. The second method is by clocking the
gas meter and following instructions in item b.

The gas valve regulator has been nominally set at 3.5-in. wc
for natural gas. When adjusting input rate, do not set
manifold pressure above 3.8-in. wc or below 3.2-in. wc.
a. Check gas input rate using Table 6.

(1.) Obtain average yearly heat value for local gas

supply.

(2.) Obtain average yearly specific gravity for local gas

supply.

(3.) Verify furnace model. Table 6 can only be used for

model 396HAD Furnaces.

(4.) Check and verify orifice size in furnace. NEVER

ASSUME

THE

ORIFICE

SIZE.

ALWAYS

CHECK AND VERIFY.

CAUTION:

DO NOT redrill burner orifices. Improper

drilling (burrs, out-of-round holes, etc.) can cause exces-
sive burner noise and misdirection of burner flames. This
can result in flame impingement of the burners and heat
exchangers causing failure.

NOTE:

If orifice hole appears damaged or is suspected to have

been redrilled, check the orifice hole with the correct size
numbered drill bit. Never redrill an orifice. A burr-free and
squarely aligned orifice hole is essential for proper flame charac-
teristics.

(5.) Find natural gas heat value and specific gravity in

Table 6.

(6.) Follow heat value and specific gravity lines to point

of intersection. Find orifice size and manifold pres-
sure settings for proper operation at given natural
gas conditions.
