Wiring & gas
A power cable will be passed through the suspension structure from the ceiling down to the unit. Three high-
temp wires will join to the power cable using a ceramic terminal block and connect to the S50. The ceramic The ceramic
Block must be located 2 feet Above top of the unit.Block must be located 2 feet Above top of the unit. The S50 top plate can reach very high tempera-
tures while in operation. Failure to use proper wiring could cause electrical failure in the unit.
Similarly, the gas line will follow the same path as the electrical wiring. However, the gas connection can use
the same line throughout. Use soft 1/2” ID gas copper tube in this application.
Important CSST Installation Note - If Corrugated Stainless Steel Tubing (CSST) is desired for use the
following conditions must be met:
- Type of CSST used has a rated operating temperature limit of 180˚F (82˚C) or better
- CSST must stop a minimum height of 6 ft (1.83m) above the top of the S50 and transition to copper
tube or black iron pipe as shown in gure 10. Using CSST within the susspension structure closer than
6ft (1.83m) will expose it to temperatures above the maximum rating.
Retrieve the power cable included in the kit. From the top of the suspension structure, thread the power
cable and gas line through the holes that align with the rear side of the unit as shown in Figure 10. Thread
both lines through the entire suspension structure and provide additional length at the very end.
The gas and wiring connections will be completed once the unit is attached to the suspension structure.

Installation
eleCtriCal requireMents:
The appliance must be electrically connected and grounded in accordance with local codes or, in the absence
of local codes, with the current CSA C22.1 Canadian Electrical Code Part 1, Safety Standards For Electrical
Installations, or The National Electrical Code ANSI / NFPA 70 in the US.
WARNING: The electrical grounding instructions must be followed.
CAUTION: When servicing controls, label all wires prior to disconnection. Wiring errors can cause improper
and dangerous operation. Verify proper operation after servicing.
If any of the original 3 conductor power cable supplied with the kit requires replacement, it must be replaced
with 18 AWG wire with a temperature rating of at least 105°C / 221°F. If the supplied mica wires require
replacement please contact your local Enviro dealer.
