Codes And Standards; Safety; General Installation; Combustion And Ventilation Air - Bryant 352MAV Installation, Start-Up, And Operating Instructions Manual

This furnace is shipped with the drain and pressure tubes con-
nected for UPFLOW applications. Minor modifications are re-
quired when used in DOWNFLOW, HORIZONTAL RIGHT,
or HORIZONTAL LEFT (supply-air discharge direction) appli-
cations as shown in Fig. 1. See details in Applications section.
This furnace must be installed with a direct-vent (combustion air
and flue) system and a factory accessory termination kit. In a
direct-vent system, all air for combustion is taken directly from the
outside atmosphere and all flue products are discharged to the
outside atmosphere. See furnace and factory accessory termination
kit instructions for proper installation.
This furnace is shipped with the following materials to assist in
proper furnace installation. These materials are shipped in the main
blower compartment.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS
1
1
Use this procedure for all installed and uninstalled furnaces. An
1
ESD service kit (available from commercial sources) may be used
2
to prevent ESD damage.
1
1
CAUTION: Electrostatic discharge can affect electronic
2
components. Follow the Electronic Discharge Precau-
3
tions Procedure listed below during furnace installation
2
and servicing to protect the furnace electronic control.
1
Precautions will prevent electrostatic discharges from
personnel and hand tools which are held during the
1*
procedure. These precautions will help to avoid exposing
the control to electrostatic discharge by putting the
furnace, the control, and the person at the same electro-
static potential.
1. Disconnect all power to the furnace. Multiple disconnects
may be required. DO NOT TOUCH THE CONTROL OR
ANY WIRE CONNECTED TO THE CONTROL PRIOR
TO DISCHARGING YOUR BODY'S ELECTROSTATIC
CHARGE TO GROUND.
2. Firmly touch the clean, unpainted, metal surface of the
furnace chassis which is close to the control. Tools held in
hand during grounding will be discharged.
3. You may proceed to service the control or connecting wires
as long as you do nothing to recharge your body (moving or
shuffling feet, touching ungrounded objects, etc.).
4. If you touch ungrounded objects, firmly touch a clean,
unpainted metal surface again before touching control or
wires.
5. Before removing a new control from its container, dis-
charge your body's charge to ground. If the control is to be
installed in a furnace, follow items 1 through 4 before
bringing the control or yourself in contact with the furnace.
Put all used and new controls into containers before
touching ungrounded objects.
I. GENERAL
Some assembly and modifications are required for furnaces
installed in any of the 4 applications shown in Fig. 1. All drain and
pressure tubes are connected as shown in Fig. 6. See appropriate
application instructions for these procedures.
