Framing
Framing can be constructed before or after the fireplace is set in place, however, most installers build the frame before setting the fireplace.
Frame fireplace with 2 x 4 lumber or heavier materi- als. Refer to framing dimensions in Figure 1 for basic fireplace specifications.
NOTE: Framing should be positioned to accommodate wall covering and fireplace facing material.
EB1 (Receptacle) Hookup
Option for Circulating Models Only
Wiring should be installed by a certified electrician. Turn off circuit breaker before wiring models.
Once fireplace is secured, complete wiring the fan kit. Remove knockout in the center of the back of the EB1 and install listed cable clamps. Feed electrical wire through listed cable clamp leaving approximately six (6) inches of wire exposed through the EB1. Secure listed cable clamp to the wire.
Attach white wire from power source to one (1) wire of receptacle and secure with nut. Attach black wire from power source to the other wire of receptacle and secure with nut. Be sure nuts are secured tightly.
Secure EB1 assembly to inside of electrical box cover- plate using two screws. Attach cover to face of the EB1 while being careful to position excess wire completely within the EB1, then attach coverplate to fireplace.
Chimney Set-Up
Since you have already planned the chimney run, you should know exactly how the installation is to be ac- complished - how much pipe is required, the number of elbows, if any, and type of termination to be used.
CAUTION: Report to your dealer any parts damaged in shipment, specifically check the end connection of chimney sections and elbows.
NOTE: The EWF36A fireplace must use MHSC model triple wall 8” chimney components only. The installation procedure described in this manual applies only to this system.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace in final position and measure out from the wall: 9¹⁄₂" (241mm). Mark a spot on the ceiling directly above the fireplace. Draw a line parallel to the back wall through this mark. (Fig. 8)
Using a plumb bob positioned directly over center point of fireplace flue collar, mark the ceiling to establish the chimney center point. (Fig. 8)

Offset Installation
In order to clear an obstruction, it may be necessary to offset chimney from vertical. This is accomplished by using elbows. Use the 30˚ Offset Elbow table on Page 6 to determine proper offset and parts required.
Each offset requires two (2) elbows. The second elbow is equipped with support straps. It is very important to install the second elbow in each offset as close to the ceiling or support as possible so that the elbow straps can be secured to framing members to help support the weight of the chimney.
Determine offset distance of your chimney arrangement from centerline of fireplace to centerline of chimney where it is to pass through ceiling.
Locate center point of the chimney on ceiling as though a straight up chimney arrangement is to be used. Mea- sure your offset dimension from straight up chimney center point on ceiling.
