Ground Rod Kit

The outdoor furnace must be electrically bonded to ground in accordance with
the requirements of the authority having jurisdiction or, in absence of such
requirements, with the National Electrical Code, ANSI/NFPA 70 and/or the
Canadian Electrical Code Part 1, CSA C22.1 Electrical Code.
Install a Ground Rod Kit (p/n 6593) and connect it to the outdoor furnace.
1. In the water line trench near the outdoor furnace, drive the ground rod
into the ground until the top of the ground rod is below the ground
surface.
2. Route the ground wire from the ground rod under the outdoor furnace
base and over to the frame of the outdoor furnace.
3. Secure the ground terminal with a cap screw (1/4" x 3/4"), star washer
and nut. Secure the ground wire to the terminal; then secure the ground
wire to the ground rod with the clamp. Tighten all hardware securely.
NOTE: A hole for the ground terminal has been pre-punched in the outdoor furnace base
near the pumps.

Furnace Installation - Connecting to Your Existing System

A common installation is to connect the outdoor furnace to an existing water
heater and then to an existing forced air system. A water-to-air heat exchanger
is mounted in the plenum or duct work of the existing furnace. Heated water
from the outdoor furnace either continuously flows through the water-to-air
heat exchanger or is diverted through a 3-way zone valve. When the thermostat
senses the need for heat, the fan on the existing furnace forces air through the
heat exchanger, transferring heat throughout the existing ductwork.
NOTE: There are numerous ways to connect to your heating system. Refer to the
Central Boiler Outdoor Furnace Installation Guide for other installations.
