Electrical Connection, Hard DIrect Wire Hook-Up

Majestic Fireplaces® UVC / UVS Vent-Free Heaters

Always check for gas leaks with a mild soap and water solution. Do not use an open

ﬂame for leak testing.

The gas control is equipped with a captured screw type pressure test point, therefore it is not necessary to pro- vide a 1/8" test point up stream of the control.

When using copper or ﬂex connector use only approved ﬁttings. Always provide a union so the gas line can be easily disconnected for burner or fan servicing.

See gas speciﬁcation for pressure details and ratings. NOTE: If ﬂex connector is used, it must be kept inside of the heater. (Fig. 7)

Electrical Connection

When installed, the heater must be electri- cally connected and grounded in accor- dance with local codes or, in the absence of local codes:

U.S. Installations: Follow local codes and the National Electrical Code, ANSI/NFPA No. 70.

NOTE: 110/120 electric power is required to operate blower (fan).

Be sure to leave sufﬁcient excess wire in case minor adjustments are required.

Any electrical re-wiring of this fan must be done by a qualiﬁed electrician.

Whether wiring directly to the fan junction box or into the EB1 (electrical receptacle box, P/N ZA1200) ﬁrst ensure cable is secured using box connector.

Turn off all power before hook-up.

Hard (DIrect) Wire Hook-Up:

First connect ground wire to ground stud located on the base of either box. Black wire from supply should connect to the variable speed switch. Alternate speed switch wire connects to temperature sensor. Alternate lead from sensor connects to fan. Alternate fan con-

nects back to white supply wire. (Fig. 8)

EB1 (Receptacle) Hook-Up

1.Remove 2" knockout. Slide the electrical box back plate into the back and bottom lances (clips) while ﬁt- ting the box connector into the knockout. Fasten into place with fastening screws provided. (Fig. 9)

2.Connect the black positive wire to brass screw (polarized side) of the receptacle. The white wire is connected to the chrome screw. The ground wire is connected to the green ground screw of the recep- tacle. Fit the receptacle into the electrical box.

3.Screw the cover plate provided to the electrical box.

CAUTION: Do not wire millivolt remote wall switch for gas heater to a 120v power sup- ply. For lighting instructions, see Page 12.

1.Thread wire through the electrical knockout located on either side of unit. Do not cut wire or insu- lation on metal edges. Ensure that wire is protected. Run the other end to a conveniently located wall

receptacle box.
