Before installing the furnace in Canada, refer to the current edition
of the NSCNGPIC. Contact Standard Sales, CSA International,
178 Rexdale Boulevard, Etobicoke, (Toronto) Ontario, Canada
M9W lR3.
Installation must comply with regulations of serving gas supplier
and local building, heating, plumbing or other codes in effect in the
area in which installation is made. In the absence of local codes,
installation must conform with the NFGC in the United States and
the NSCNGPIC in Canada
These instructions cover minimum requirements for a safe instal-
lation and conform to existing national standards and safety codes.
In some instances, these instructions exceed certain local codes
and ordinances, especially those that may not have kept pace with
changing residential construction practices. We require these
instructions as a minimum for a safe installation.

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

Electrostatic discharge can affect electronic components.
Take precautions during furnace installation and servicing to
protect the furnace electronic control. Precautions will pre-
vent electrostatic discharges from personnel and hand tools
which are held during the 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
electrostatic potential.
1. Disconnect all power to the furnace. DO NOT TOUCH THE
CONTROL OR ANY WIRE CONNECTED TO THE CON-
TROL PRIOR TO DISCHARGING YOUR BODY'S ELEC-
TROSTATIC CHARGE TO GROUND.
2. Firmly touch a clean, unpainted, metal surface of the furnace
chassis which is close to the control. Tools held in a person's
hand during grounding will be satisfactorily discharged.
3. After touching the chassis you may proceed to service the
control or connecting wires as long as you do nothing that
recharges your body with static electricity (for example; DO
NOT move or shuffle your feet, DO NOT touch ungrounded
objects, etc.).
4. If you touch ungrounded objects (and recharge your body with
static electricity), firmly touch furnace again before touching
control or wires.
