DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls and components installed and pre-wired. Remove the shipping carton, exposing the front glass door. Remove the top panel. Remove the cardboard from underneath the pressure relief plates. Gently depress the outer top corners of the access panel until the catches "pop" the panel free, allowing it to swing out and down to open. Open the two latches (located under the firebox floor) securing the glass door. Remove the door by tilting it outward at the bottom and lifting it up. Set the door aside protecting it from inadvertent damage. See

Figure 55 on page 23.

Step 1. FRAMING

Frame these appliances as illustrated in Figure 9 on page 7, unless the appliance is to be installed in a corner.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

See Figure 10 on page 7 or Figure 11 on page 8 for corner framing installations. All framing details must allow for a minimum clearance to combustible framing members as shown in

Table 2.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.

Headers may be in direct contact with the appliance top spacers but must not be supported by them or notched to fit around them. All construction above the appliance must be self supporting. DO NOT use the appliance for structural support.

The fireplace should be secured to the side framing members using the unit's nailing flanges - one top and bottom on each side of the fireplace front. See Figure 6. Use 8d nails or their equivalent.

	Note: The nailing flanges, combustible members
	and screw heads located in areas directly adjacent
	to the nailing flanges, are EXEMPT from the 1/2”
	clearance to combustible requirements for the
	firebox outer wrapper. Combustible framing may be
	in direct contact with the nailing flanges and may
	be located closer than 1/2” from screw heads and
	the firebox wrapper in areas adjacent to the nailing
	flanges. Frame the opening to the exact dimensions
	specified in the framing details of this manual.

Step 3. INSTALL THE VENT SYSTEM

General Information

These instructions should be used as a guideline and do not supersede local codes in any way. Install vent according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 and - B149.2 in Canada.

These fireplaces are designed, tested and listed for operation and installation with, andonlywith,SecureVent™ (SV4.5)Direct Vent System Components, Secure Flex™

Flexible Vent Components manufactured by Security Chimneys International. These approved vent system components are labeled for identification. DO NOT use any other manufacturer's vent components with these appliances. These fireplaces must be vented directly to the outside.

The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosing wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

Preparing the Appliance Vent Collar on D-500/600/800 Series (Combined Top and Rear Vent) Models

Each of the unit's two vent collars are sealed with a cover plate and a seal plate and gasket. The cover, and seal plate and gasket must be removed from the vent collar being used. Refer to Figure 13 for top vent usage and Figure 14 for rear, and the following steps to prepare the appropriate collar for use.

From the vent collar being used, remove the four screws securing the vent seal plate and gasket. Remove and discard the seal plate and gasket.

When the top vent collar is being used, from inside the firebox, loosen the two screws in the keyhole slots of the cover plate and remove the remaining two cover plate securing screws. Remove and discard the cover plate. Reinstall and securely tighten all four screws.

When the rear vent collar is being used, from inside the firebox, remove the two screws securing the lintel to the rear wall of the firebox, then remove the lintel. Remove the four cover plate securing screws.

Remove and discard the cover plate. Reinstall and securely tighten all four cover plate screws. Re-secure the lintel to the rear wall of the firebox.

WARNING: FAILURE TO REINSTALL AND SECURELY TIGHTEN COVER PLATE SCREWS COULD RESULT IN LEAKAGE OF FLUEPRODUCTSINTOTHELIVINGSPACE. VENTCOVERPLATEANDVENTSEALPLATE MUST REMAIN SECURELY INSTALLED ON UNUSED VENT COLLAR. FAILURE TO DO SO COULD RESULT IN LEAKAGE OF FLUE PRODUCTS INTO LIVING SPACE.
