PLACEMENT IN A FIREPLACE WITH A RESTRICTIVE BARRIER

IMPORTANT INFORMATION FOR THE IN-

STALLATION OF THIS GAS LOG SET

The following are guidelines for placing a gas log set in a fireplace that has a restrictive barrier along the bottom front opening of the fireplace. Some examples of barriers are glass/screen door frames and sunken/ recessed fireplaces.

Height of

Restriction (x)

No Restriction

0 to 3”

Minimum Depth of

Fireplace/Firebox

23Z\x”

15”

Greater than 3” *

*Any barrier greater than 3” placed in front of the gas log set is not recommended by the manufacturer.

NOTE: Non combustible material such as refractory brick may be used to line the floor of the fireplace in order to raise the height of the gas log set in relation to a restrictive barrier.

If the unit is raised, the minimum height dimension listed in the homeowner’s manual must not be exceeded.

NOTE: If the log set is equipped with a remote receiver, a restrictive barrier may reduce the battery life by increasing the ambient temperature inside the fireplace. Placement of the receiver outside of the fireplace will extend the battery life.

Glass door frames with adjustable louvers should have the louvers fully open while the unit is in operation

X

Height of restrictive barrier caused by glass door frames, recessed fireplaces, etc. from the base or bottom surface of the unit. (Refer to Table)

Figure 3 -

Reference Drawing of Log Set in an Enclosure

FP2854 logs in enclosure

The log set should be placed against or as near as possible to the rear wall of the fireplace/firebox.

FP2854

Refer to

Table

Barriers such as the bottom of a glass door frame placed in front of a gas log set can change the air flow characteristics of the fireplace which in turn can cause the unit to overheat and malfunction. Any deviation from the installation guidelines on this sheet will potentially void the warranty.

INSTALLATION

PLACE AND SECURE APPLIANCE

You must secure the gas log heater to the fireplace floor. Properly securing the grate prevents movement of the entire unit when you adjust the controls. Grate movement could cause a gas leak.

ASSEMBLY PROCEDURE

1. Center the gas log unit in the fireplace or firebox. Make certain the front feet of the grate sit inside the front edge of the fireplace or firebox.

2. Refer to Figure 4 for hole locations. After centering the grate correctly, mark the hole positions on the fireplace/firebox floor. Drill two (2) 5/32" diameter holes approximately 1Z\x" deep.

3. Anchor the grate to the fireplace/firebox floor using the screws provided. Figure 4

Proper installation of the grate is essential to prevent any movement of the gas logs and controls during operation.

GAS LINE CONNECTION

NOTICE: A qualified gas appliance installer must connect the heater to the gas supply. Consult all local codes.

Use new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide limits, and where permitted by local codes.

Gas piping system must be sized to provide minimum inlet pressure (Listed on Data

Plate) at the maximum flow rate (BTU/Hr).

Undue pressure loss will occur if the pipe is too small.

A manual shutoff valve must be installed upstream of the appliance. Union tee and plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance. Figure 5

ferent, DO NOT INSTALL THE GAS LOGS. Contact your dealer for the correct model.

Always use an external regulator for all propane/LPG gas logs only, to reduce the supply tank pressure to a maximum of 13" w.c. This is in addition to the regulator fitted to the gas log set. High pressure natural gas systems require a regulator to reduce supply pressure to 10" w.c.

Connecting directly to an unregulated propane/LPG tank can cause an explosion

32D1999 7

The heater gas inlet connection is 3/8" NPT at the regulator, inlet on the right side facing the gas log. If a left side connection is required, the connecting pipe may be led under the rear of the gas logs or behind the grate for connection to the inlet.

NOTE: The millivolt valve has an internal regulator, thus the incoming gas line connects directly to the valve.

Test all gas joints from the gas meter to the appliance regulator for leaks using a gas analyzer or soap and water solution after completing connection. DO NOT USE AN

OPEN FLAME.

Check the gas pressure with the appliance burning.

MANUAL CONTROL

Figure 6

The pressure regulator is preset and locked to discourage tampering. If the pressure is not as specified, replace with the correct part from the parts list in this manual.

Remove 1/8" NPT plug, located on side of regulator body.

Install fitting and tubing to pressure gauge. After taking pressure reading, re-install test plug. Check for gas leaks.

MILLIVOLT CONTROL

Figure 7

The valve regulator controls the burner pressure which should be checked at the pressure test point. Turn captured screw counter clockwise 2 or 3 turns and then place tubing to pressure gauge over test point (Use test point labeled

“OUT”). After taking pressure reading, be sure and turn captured screw clockwise firmly to re-seal. Do not over torque. Check for gas leaks.

PLACEMENT OF THE GLOWING EMBERS

Cover the burner pan with glowing embers (rock wool) provided. Tear pieces approximately 1/2" in size (roughly the size of a nickel) and cover the burner evenly.

DO NOT…

1. Pile the rock wool too thickly on pan.

2. Place rock wool higher than the top of the front grate bar.

3. Cover the pilot with rock wool.

PLACEMENT OF DECORATIVE VOLCANIC

ROCk

Sprinkle volcanic rock in front of front glowing embers and to both sides. DO NOT SPRINkLE ON BURN-

ERS, PILOT OR LOGS.

IMPORTANT: FIREPLACE DRAFT TEST DURING INI-

TIAL INSTALLATION

It is critical to verify that your chimney is drafting properly because the fireplace and gas logs function as a system.

Although MHSC goes to great lengths to design vented gas log sets that minimize sooting, all vented log sets will soot over time. Sooting normally appears as areas of a black powder-like substance on the logs. It is important to periodically clean and inspect the logs per the cleaning and servicing section of the manual.

FIREPLACE DRAFT TEST

Fireplace systems that do not draft properly can increase the amount of soot produced by normal operation of the log set and in extreme cases can cause soot to be deposited within the room. This effect can be a sign of a blocked chimney, a faulty vent system or the result of negative pressure within the home. The dealer should be able to diagnose if a problem exists and be able to provide a solution to improve the venting of the fireplace.

FIREPLACE DRAFT TEST METHOD

To determine if your fireplace is drafting properly, turn the log set on. After the log set has been burning for about 10 minutes, place a match or smoke stick along the top and sides of the fireplace opening. If the flame or smoke is not pulled into the fireplace, then the fireplace is not venting

properly. At this point the damper stop should be adjusted so that the damper opening is increased. If the problem remains after the open area of the damper is increased, then the fireplace system should be professionally inspected to determine if your firebox/chimney is venting properly.

22 32D1999

FLAME APPEARANCE

CHECkING BURNER FLAMES

In normal operation at full rate after approximately 15 minutes, the following flame appearance should be observed.

Burner flames should become yellow as they contact embers on the face of the log. The log face will glow a bright reddish orange.


Rear flame should be yellow and extend vertically. Maximize spacing on top logs.

Ember bed should have a yellow/orange glow.

BASIC WARRANTY

MHSC warrants the components and materials in your gas appliance to be free from manufacturing and material defects for a period of two years from date of installation. After installation, if any of the components manufactured by MHSC in the appliance are found to be defective in materials or workmanship,

MHSC will, at its option, replace or repair the defective components at no charge to the original owner.

MHSC will also pay for reasonable labor costs incurred in replacing or repairing such components for a period of two years from the date of installation. Any products presented for warranty repair must be accompanied by a dated proof of purchase.

This Limited Warranty will be void if the appliance is not installed by a qualified installer in accordance with the installation instructions. The Limited Lifetime Warranty will also be void if the appliance is not operated and maintained according to the operating instructions supplied with the appliance, and does not extend to (1) firebox/burner assembly damage by accident, neglect, misuse, abuse, alteration, negligence of others, including the installation thereof by unqualified installers, (2) the costs of removal, reinstallation or transportation of defective parts on the appliance, or (3) incidental or consequential damage. All service work must be performed by an authorized service representative.

This warranty is expressly in lieu of other warranties, express or implied, including the warranty of merchantability of fitness for purpose and of all other obligations or liabilities. MHSC does not assume for it any other obligations or liability in connection with the sale or use of the appliance. In states that do not allow limitations on how long an implied warranty lasts, or do not allow exclusion of indirect damages, those limitations of exclusions may not apply to you. You may also have additional rights not covered in this Limited Warranty.

MHSC reserves the right to investigate any and all claims against the Limited Warranty and decide upon method of settlement.
