General Venting

Your fireplace is approved to be vented either through the side wall, or vertical through the roof.

Only MHSC venting components specifically approved and labelled for this fireplace may be used.

Flexible UL1777 listed venting may be used in any venting application where rigid direct vent components can be used. All restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible venting.

Flex kits may not be modified. Flex kits may be added to the end of a vent run made of rigid vent sections using pipe manufacturer's approved flex to pipe adapters. This may occur only if doing so does not violate any of the venting length, height, routing, horizontal to vertical raito requirements or clearance considerations detailed in this manual.

Venting terminals shall not be recessed into a wall or siding.

Horizontal venting which incorporates the twist lock pipe must be installed on a level plane without an inclining or declining slope.

Horizontal venting which incorporates the use of flex venting shall have an inclining slope from the unit of 1” (25 mm) per 24” (610 mm).

There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24” (610 mm) from the front of the termination hood.

Do not locate termination hood where excessive snow or ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow blowers, make sure snow is not directed towards vent termination area.

Location of Vent Termination

It is imperative the vent termination be located observing the minimum clearances as shown on following page.

WARNING

Always maintain minimum clearances around vent systems. The minimum clearances to combustibles for horizontal vent pipe are 3" at the top* and 1" at the sides and bottom of the vent system until the pipe penetrates the nearest vertical wall (1" required). A 1" minimum clearance all around the pipe must be maintained at outside wall and on vertical runs. Do not pack the open air spaces with insulation or other materials. This could cause high temperatures and may present a fire hazard.

* Unless the vertical run is 7Z\x feet or higher (top vent units only), the clearances for the horizontal run is 1" at the top.

General Information Assembling Vent Pipes

USA Installations

The venting system must conform to local codes and/or the current National Fuel Code ANSI Z223.1/NFPA 54.

Only venting components manufactured by MHSC may be used in Direct Vent systems and UL 1777 Listed Type Flex Venting.

Canadian Installations

The venting system must be installed in accordance with the current CSA-B149.1installation code.

Flex Vent Pipes

Before joining the flex vent pipe to the unit, apply a bead of high temperature sealant* (provided) to the 4” pipe exiting the fireplace. Secure flex vent pipe in place with a hose clamp (provided).

*Be sure the flex pipe overlaps at least 1” (25 mm) onto the collars of the fireplace and termination. If the termination has an internal bead, be sure to overlap and secure 1” (25 mm) past the bead.

* Be sure the vent is actually crushed before proceeding. Apply a tug to be sure the vent will not slip off the collars. Repeat process with 7” flex vent pipe. The same procedure must be performed on the vent side.

Twist Lock Pipes

When using twist lock pipe it is not necessary to use sealant on the joints. The only areas of the venting system that need to be sealed with high temperature silicone sealant are the sliding joints of any telescopic vent section used in the system.

To join twist lock pipes together, simply align the beads of the male end with the grooves of the female end, twisting the pipe until the flange on the female end contacts external flange on the male end. It is recommended that you secure the joints with three (3) sheet metal screws, however, this is not mandatory with twist lock pipe. Figure 14

To make it easier to assembly the joints, we suggest putting a lubricant (Vaseline or similar) on the male end of the twist lock pipe prior to assembly.

How to Use the Vent Graph

The Vent Graph should be read in conjunction with the following vent installation instructions to determine the relationship between the vertical and horizontal dimensions of the vent system.

1.Determine the height of the center of the horizontal vent pipe exiting through the outer wall. Using this dimension on the Sidewall Vent Graph, Figure 15, locate the point intersecting with the slanted graph line.

2.From the point of this intersection, draw a vertical line to the bottom of the graph.

3.Select the indicated dimension, and position the fireplace in accordance with same.

EXAMPLE A:

If the vertical dimension from the floor of the unit is 11’ (3.4 m) the horizontal run to the face of the outer wall must not exceed 14’ (4.3 m).

EXAMPLE B:

If the vertical dimension from the floor of the unit is 7’ (2.1 m), the horizontal run to the face of the outer wall must not exceed 6’ (1.8 m).

VENT INSTALLATION

HBDV7 Series Direct Vent Gas Fireplace

WARNING

Horizontal sections of this vent system require a minimum of 3” clearances to combustibles at the top of the flue and 1” clearance at the sides and bottom until the flue penetrates the outside wall. A minimum 1” clearance all around the flue is acceptable at this point of penetration. If vertical rise is 7Z\x” feet or higher when top venting, the clearance to combustibles is 1” on all sides of the horizontal run.

Vertical sections of this vent system require a minimum of 1” clearance to combustibles on all sides of the pipe.

WARNING

This fireplace must be vented to the outside. The venting system must NEVER be attached to a chimney serving a separate solid fuel burning appliance. Each gas appliance must use a separate vent system. Do not use common vent systems.

VENTING INSTALLATION

Rear Wall Vent Application

When installed as a rear vent unit this appliance may be vented directly to a termination located on the rear wall behind the appliance.

Only MHSC venting components are approved to be used in these applications (Refer to ‘Venting Components’ listed for different installation requirements).

The maximum horizontal distance between the rear of the appliance (or end of the transition elbow in a corner application) and the outside face of the rear wall is 20” (508 mm). Figure 17

Only one 45° elbow is allowed in these installations.

Minimum clearances between vent pipe and combustible materials are as follows:

Top - 3” (76 mm)

-except at outside wall 1" (25 mm)

Sides - 1” (25 mm) Bottom - 1” (25 mm)

Rear Vent Top View

REAR WALL VENT INSTALLATION - TWIST LOCK PIPE

Step 1

Locate and cut the vent opening in the wall.

For combustible walls first frame in opening. Figure 18

NOTE: When using flex vent, the opening will have to be measured according to the 1” (25 mm) rise in 24” (610 mm) vertical run.

Combustible Walls: Cut a 9B\,”H x 9B\,” W (244 x 244 mm) hole through the exterior wall and frame as shown.

Figure 18

Noncombustible Walls: Hole opening should be 7Z\x” (191 mm) diameter.

Step 3

Measure the horizontal length requirement for the venting including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51 mm). Figure 17

Step 4

Install the 4” (102 mm) vent to the appliance collar and secure with 3 sheet metal screws. Install the 7” (178 mm) vent pipe to the appliance collar and secure with 3 sheet metal screws. It is not necessary to seal this connection. If a 45° elbow is being used attach the elbow to the appliance in the same manner then attach the venting to the elbow.

It is critical that there is no downward slope away from the appliance when connecting

the vent or elbow.

Step 5

Guide the venting through the vent hole as you place the appliance in its installed position. Guide the 4” (102 mm) and 7” (178 mm) collar of the vent termination into the outer ends of the venting. Do not force the termination. If the vent pipes do not align with the termination, remove and realign the venting at the appliance flue collars. Figure 19. Attach the termination to the wall as outlined in the instruction sheet supplied with the termination.

NOTE: For all top vent installations where a 90° elbow is the first pipe piece towards a sidewall termination (up and out), anopen-centerringed flue restrictor, part #69D3006 must be installed onto the top edge of the firebox flue adapter. To create thisopen-centerrestrictor, twist and break off the center rib of the supplied flue restrictor. The installed part should appear similar to that show n inFigure 22.

Since it is very important that the venting system maintain its balance between the combustion air intake and the flue gas

exhaust,

certain

 

limitations

as to

FP2303

vent configurations apply and must be strictly adhered to.

The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable.

Minimum clearance between vent pipes and combustible materials is 3" (76 mm) on top, and 1" (25 mm) on the bottom and sides unless otherwise noted.

When vent termination exits through foundations less than 20” (508 mm) below siding outcrop, the vent pipe must flush up with the siding.

It is best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.

The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace (or the top of the Transition Elbow) to the face of the outer wall.

Horizontal plane means no vertical rise exists on this portion of the vent assembly.

VENTING INSTALLATION

When installing the appliance as a rear vent unit, the 90° or 45° Transition Elbow attached directly to the rear of the unit is NOT INCLUDED in the following criteria and calculations, and unless specifically mentioned should be ignored when calculating venting layouts.

The maximum number of 90° elbows per side wall installation is three (3). Figure 23

If a 90° elbow is fitted directly on top of the fireplace flange the maximum horizontal vent run before the termination or a vertical rise is 36” (914 mm). Figure 24

If a 90° elbow is used in the horizontal vent run (level height maintained) the horizontal vent length is reduced by 36” (914 mm). Figures 24 & 25. This does not apply if the 90° elbows are used to increase or redirect a vertical rise.Figure 23

Example: According to the vent graph (Page 14) the maximum horizontal vent length in a system with a 7Z\x’ (2.3 m) rise is 20’ (6 m) and if a 90° elbow is required in the horizontal vent it must be reduced to 17’ (5.2 m).

In Figures 26 & 27, dimension A plus B must not be greater than 17’ (5.2 m)

The maximum number of 45° elbows permitted per installation is six (6). These elbows can be installed in either the vertical or horizontal run.

For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 18” (457 mm). This does not apply if the 45° elbows are installed on the vertical part of the vent system.

Vertical Height Requirements

Step 5

Measure the horizontal length requirement including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51 mm) (or the distance required if installing a second 90° elbow). Figure 30

Always install horizontal venting on a level plane.

Step 6

Use appropriate length of pipe sections - telescopic or fixed - and install. The sections which go through the wall are packaged with the starter kit, and can be cut to suit if necessary.

Sealing vent pipe and firestop gaps with high temperature sealant will restrict cold air being drawn in around fireplace.

VENTING INSTALLATION

Step 7

Guide the vent terminations 4” and 7” collard into their respective vent pipes. Double check that the vent pipes overlap the collars by 2” (51 mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof. As an alternative to screwing the termination directly to the wall, you may also use expanding plugs or an approved exterior construction adhesive. You may also attach the termination with screws through the inner body into the 4” vent pipe, however for this method, you must extend the 4” pipe approximately 6” (152 mm) beyond the outer face of the wall.

Support horizontal pipes every 36” (914 mm) with metal pipe straps.

Vertical Sidewall installation - flex vent pipe

NOTE: The 40” (1016 mm) flex vent is used for 90° off the top of the unit then out the back wall.

Follow Step 1 and 2 on Page 19.

Step 3

Install the four (4) spacer springs on the 4” flex vent pipe. When installing the spacer springs around the 4” pipe, stretch the spring to approximately 15” (381 mm), wrap the spring around the pipe and interlock the ends of the spacer spring approximately 2” (51 mm). Measure 6C\v” (172 mm) from the end of the pipe. Place the next spring 5” (127 mm) from the previously installed spring. Place the next spring 6” (152 mm) from the last spring. Finally place the last spring 12” (305 mm) from the last spring installed. Figure 31

Step 4

Install the 4” (102 mm) flex vent pipe to the appliance collar as described on Page 14. Secure the end with the first spring 6C\v” (172 mm) from the flex pipe end to the unit.

Step 5

Slide the 7” (178 mm) flex vent pipe over the 4” flex vent pipe and secure the 7” collar as described on Page 13.

Step 6

Bend the flex pipe horizontal so the bottom of the horizontal pipe measure 6Z\x” (165 mm) from the top of the unit immediately after the 90° formation. Figure 32. Be sure to follow the 1/2” (13 mm) rise in a 12” (305 mm) horizontal run rule.

Step 7

Install the 4” flex then 7” flex to the termination.
