Parallel Installation; Minimum Clearances To Combustible Materials And Floor Protection - CADDY PF01015 Installation And Operating Instructions Manual

DO NOT REMOVE, RELOCATE OR BYPASS ANY OF THE SAFETY CONTROLS IN THE
ORIGINAL FURNACE INSTALLATION.
You must determine the air flow through the existing furnace before installing the Caddy wood add-on:
1. Run the furnace to which the Caddy add-on is connected until it reaches its regular heating temperature.
2. With a thermometer, measure the temperature of the fresh air entering the furnace and that of the air exiting the
furnace in the hot air plenum.
Note: There can be a large lag in the readings of many commercially available thermometers. Give them adequate
time to stabilize when taking temperatures.
The temperature rise is obtained by subtracting the cold air return temperature from that of the air exiting in the hot air
plenum. The result (t) will be needed for next step.
3. Make the following verifications:
Existing oil, electric or gas furnace:
Q= ______q_____
1.08 x (T2 – T1)
Q = Flow in cubic feet/min
q = Heat flow in BTU/h
T1= Fresh air return temperature
T2= Hot air outlet temperature

11.2. PARALLEL INSTALLATION

Parallel installation with another furnace that shares the same ducts system is not permitted in Canada. That type of
installation is permitted in the USA only, under certain conditions.
For installation conditions, see Section 0 -
