TOA Electronics 600 Vertical Vent Termination Clearances, Typical Installation Sequence

VENT TERMINATION CLEARANCES

These instructions should be used as a guide- line 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.

Vertical Vent Termination Clearances

Terminate single vent caps relative to building components according to figure 4.

See Figure 10 on page 7 or Figure 11 on page

8for 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 appli- ance top spacers but must not be supported by them or notched to fit around them. All construc- tion 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

Terminate multiple vent terminations accord- ing to the installation codes listed at the top of this page.

Horizontal Vent Termination Clearances

The horizontal vent termination must have a minimum of 3" (76 mm) clearance to any overhead combustible projection of 2 ¹⁄₂" (64

mm)or less. See Figure 5. For projections exceeding 2 ¹⁄₂" (64 mm), see Figure 5. For additional vent location restrictions refer to Figure 8 on page 6.

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation follows, however, each installation is unique resulting in variations to those described.

See the page numbers references in the follow- ing steps for detailed procedures.

Step 1. (page 5) Construct the appliance fram- ing. Position the appliance within the framing and secure with nailing brackets.

Step 2. (page 5) Route gas supply line to appliance location.

blower (optional equipment).

b. Electronic Appliances – Field wire and install operating control switch.

Step 5. (page 21) Install blower kit (optional equipment).

Step 6. (page 22) Make connection to gas supply. Step 7. (page 22) Install the logs, decorative volcanic stone and glowing embers.

Step 8. (page 22) Checkout appliance operation. Step9. (page23)Installglassdoorframeassembly. Step 10. (page 23) Adjust burner to ensure proper flame appearance.

Step 11. (page 23) Install the hoods.

DETAILED INSTALLATION STEPS

The appliance is shipped with all gas controls and components installed and pre-wired. Re- move the shipping carton, exposing the front glass door. Remove the top panel. Remove the cardboard from underneath the pressure re- lief plates. Gently depress the outer top cor- ners 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. Re- move 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.

To The Framing

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 2. ROUTING GAS LINE

Route a ¹⁄₂" (13 mm) gas line along the inside of the right side framing as shown in Figure 7. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations.

All appliances are factory-equipped with a flex- ible gas line connector and ¹⁄₂ inch shutoff valve. (See step 6 on page 22).
