Heater must be electrically grounded in accordance with NEC and C22.1(in Canada).

NOTES:

1. Field installed ground to inside of junction box.

2. If any of the original wire as supplied with the heater must be replaced, it must be replaced with 105°C wire or its equivalent.

Venting

General

CAUTION: Proper installation of flue venting is critical for the safe and efficient operation of the heater.

Definition of Appliance Categories

Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.

Category I. A heater which operates with a non-posi- tive vent static pressure and with a vent gas temperature that avoids excessive condensate pro- duction in the vent.

Category II. A heater which operates with a non-posi- tive vent static pressure and with a vent gas temperature that may cause excessive condensate production in the vent.

Category III. A heater which operates with a positive vent pressure and with a vent gas temperature that avoids excessive condensate production in the vent.

Category IV. A heater which operates with a positive vent pressure and with a vent gas temperature that may cause excessive condensate production in the vent.

See Table I for appliance category requirements for the Hi Delta.

NOTE: For additional information on appliance categorization, see appropriate ANSI Z21 Standard and the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.

Determination of Appliance Category for Venting Purposes and Venting Arrangements

WARNING: Contact the manufacturer of the vent material if there is any question about the appliance categorization and suitability of a vent material for application on a Category III or IV vent system. Using improper venting materials can result in personal injury, death or property damage.
