Installation

A qualified engineer or architect MUST sign off on the structure supporting the hanging kit prior to installation. Maximum total system weight is 400lb.

Ceiling Mount Installation

1. Align the Ceiling Mount Assembly directly over where the S50 will be suspended, between two joists in the ceiling as shown in Figure 5.
To better line up the ceiling mount with the final location of the S50, a string with a small weight at-tached can be slowly dropped through the center of the Ceiling Mount Assembly.
2. Secure the Ceiling Mount Assembly to the joists once the final location has been determined.
3. Working from the ceiling downwards, begin attach-ing sections one-by-one to create the full suspen-sion structure.

• NOTE: One structure section should be set aside to attach to the S50.

Each section will come packaged with four (4) joint plates that are used to secure the sections together. Use the included fasteners to attach the sections together as shown in Figure 6.

4. As sections are attached, slide vent pieces through the center of the structure and attach to any other existing vent pieces. (See picture in next page) Keep the very top piece unattached for the time being as it will need to attach to the unit once it has been secured to the suspension structure.
5. Continue attaching suspension structure and vent-ing pieces until there is only one suspension struc-ture piece left (set aside at a previous step)

UNIT PREPARATION

1. Remove the stock top plate from the S50. Refer to section “Removing Top Plate” in the Owner’s Manual for details on how to properly remove.
2. Remove the Door Frame and Rear Chassis from the S50. Refer to the Owner’s Manual for details on how to properly remove.
3. On the top of the S50, near the exhaust adapter, remove the wire channel shown in Figure 7. Any wires currently passing through the channel will need to be routed around the suspension structure once it is installed.
4. Retrieve the single set aside suspension structure section from the previous section. Depending on whether the set aside section is a 1ft or 2ft section, find the correspond-ing S50-S brace cutout that was included with the starter kit (refer to Figure 1). One of the braces on the remaining suspension structure will need to be replaced with this S50-S brace cutout. Remove the eight (8) 1/4-20 hex head bolts securing the brace and replace with the S50-S brace cutout.

5. Retrieve the two (2) Air Box Joints and the two (2) Air Joint Spacers that are included with the starter kit. the spacers and joints to the re- maining suspension structure as shown in Figure 8. A few things of note:

• The joints should be attached on opposite sides.
• The jog should be moving away from the center of the sus- pension structure.
• The joints should be attached on the same end as the cutout of the new brace.

6. Align the now modified support structure with the top of the S50 as shown in Figure 9. The Air Box Joints will line up with three (3) holes on each side of the airbox. Secure in place using six (6) 1/4-20 Hex head bolts.

*NOTE: If you have an older version of the S50, these attachment points will be missing. Align the support structure over the top exhaust adapter and let it rest on the air box. Spot drill holes through the pre-punched holes of the Air Box Joints into the air box.

7. Slide a vent piece through the center of the suspension structure and attach to the exhaust adapter on the S50.
8. Retrieve the replacement S50 top cover and attach it to the unit following the same steps used to remove the stock top cover.

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.

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 The ceramicceramic Block must Block must be be located 2 feet located 2 feet Above Above top of the top of the unit.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 figure 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. Refer to pages 12 & 13.

UNIT INSTALLATION

Position the S50 near the suspension structure. Prior to attaching the unit to the suspension structure, ensure all additional covers and components are placed onto the suspension structure/unit as described below:

S50

1. Place the top collar and Duravent 10” slip section (both included in the starter kit, see Figure 1) over the suspension structure attached to the unit and rest them on top of the S50.
2. Each suspension structure piece includes a DuraVent Dura Black 10” section. Retrieve the section for the suspension structure attached to the unit and slide it onto the unit. The slip section from the previous step should slide inside this component. Refer to Figure 11.

Suspension Structure

3. Slide the trim collar around the suspension structure and secure to the ceiling.
4. Each suspension structure piece includes a DuraVent Dura Black 10” section. Gather these parts and slide them one-by-one over the suspension structure as shown in Figure 12.
5. Carefully lift the S50 and position it below the suspension structure. Thread the high-temp wires through the remaining suspension structure in the same way as the previous sections.
6. With the remaining joint plates, attach the S50 to the suspension structure. Ensure the inner exhaust vents properly mate as the structure is connected.
