Installing The Stack Safety Switch For Canadian Installations - Saturn 125 Operator's Manual

Installing the Stack Safety Switch For Canadian Installations

NOTE: CSA Standards require that all heating equipment must be installed with a stack safety switch. If your
heating equipment is being installed in Canada, follow the instructions listed below.
CAUTION: For your safety and the safe operation of your heating equipment, the stack switch must
be installed by a qualified installer in accordance with the installation instructions provided here. Wiring
must be accomplished in accordance with all applicable codes. Failure to adhere to these safety
recommendations may result in serious personal injury and/or equipment damage.
1. Follow the instructions in the Operator's Manual, Section 4 to install a proper stack, including the
barometric damper which must be installed within 40 inches of the breach.
NOTE: The barometric damper must be installed so that it is level and the flapper moves freely.
2. Ensure that main power to the heating equipment is turned OFF.
3. Position the stack safety switch over the lip of the barometric damper as shown in Figure 4O.
4. Drill a 1/8" pilot hole for the mounting screw, and mount the stack safety switch using the mounting
screw supplied with the switch.
NOTE: The mounting screw must not interfere with the free movement of the flapper on the barometric
damper.
5. Install the wall thermostat according to the instructions provided in the Operator's Manual, Section 4.
Wire the wall thermostat and stack safety switch in series as shown in Figure 4P. Install the wire so that
it is secured away from any hot surfaces.
6. When the heating equipment installation is completed, follow the instructions in the Operator's
Manual, Sections 5 and 6 to prime the pump and start/adjust the burner.
7. Follow instructions in the Operator's Manual, Section 8 to check the draft; this is crucial for the
proper, safe operation of the heating equipment.
