Thermo Pride CDX1-100N Installation And Operation Manual page 38

All installations and services must be performed by qualified service personnel.
B. INITIAL START UP:
This furnace does not have a pilot. It is equipped with a hot surface igniter, which automatically lights the
burner. Do not attempt to light the burner by hand. Check the following items before the initial start-up.
1. Check all wiring for loose connections and proper hook up.
2. Leak test gas piping connections.
3. Check all tubing to the pressure switch and drains to make sure they are connected firmly at all their
connection points.
4. Check flue pipe, combustion air inlet and all PVC connections for tightness and to make sure there is
no blockage.
5. Make sure air filter is in place.
6. Make sure the outside vent and air intakes are installed according to instructions and that they are
free from blockage.
7. Make sure that the drain trap is properly connected to the furnace and to the buildings drain system.
OPERATING INSTRUCTIONS:
: Turn off power to furnace before it is placed into service. The gas piping system
must have been leak tested by a qualified heating contractor. (See Section III, J, of these
instructions on the installation of gas piping).
: It may be necessary to purge the air out of the gas line for initial start-up of the
furnace after installation. This should be done by a qualified heating contractor. If excessive gas
escapes when purging the gas supply at the union, allow the area to ventilate for at least 15
minutes before attempting to start the furnace. LP gas is especially dangerous because the
specific gravity of LP gas allows it to accumulate at floor level at a dangerous concentration. For
remainder of operating instructions, reference Users Information Manual.
: Heat exchanger oil will burn off on initial firing creating an unpleasant odor. To
prevent this odor from occurring more than once, it is suggested that:
1. A window(s) be opened.
2. The thermostat be set at highest setting.
3. The furnace remain running at conditions 1&2 for 30 minutes or until odor has dissipated.
Check for the model number of this furnace, its input, the type of gas and the manifold pressure on the
information plate located on the vestibule panel behind the upper front panel. If using the above example,
the furnace was a CHX1-100 model and the 98,663 BTU input would be acceptable because it was within
2% of the listed high fire input of 100,000.
