INSTALLING LOGS, LAVA ROCK AND GLOWING EMBERS

WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically approved with this heater may result in property damage or personal injury.

Each log is marked with a number. These numbers will help you identify the log when installing. It is very important to install these logs exactly as instructed. Do not modify logs. Only use logs supplied with fireplace.

Remove glass door. See Removing/Replacing Glass Door, page 22. Install logs according to instructions for fireplace model numbers.

Fireplace Models

MBDV37 and MBDV41

1.Place log #1 (back log) on top of grate. Make sure the notches in the bottom of the log fit over the grate (see Figure 50).

2.Rest log #2 (large front log) on the pins on the front part of the grate (see Figure 51).

3.Place log #3 (“C”-shaped crossover log) onto the rear and front logs. Make sure it is seated properly on the smooth sur- face on the front log and on the pin on the back log as shown in Figure 52.

4.Place log #4 (small, round log) on the pin on the right side of front log as shown in Figure 53

5.Place log #5 (small log) onto the front left part of the grate making sure the notches fit over the prongs of the grate (and hole over pin on 41" set). See Figure 54.

6.Place lava rock along sides and front of firebox bottom in areas that are vis- ible only. It is not necessary to use all of the lava rock provided.

NOTICE: Do not put lava rock on burner or under burner. Placing lava rock on burner could cause performance problems.

7.Pull ember material apart into pieces no larger than a dime. Place these pieces loosely and sparingly directly onto the exposed section of the front burner and along the space between the burner and grate prongs (see Figure 55). This will create the glowing ember ap- pearance as the flame touches the em- ber material. Do not block air slots by using too much ember material in one area. It is not necessary to use all of the ember material provided.

8.Replace the glass door. See Removing/ Replacing Glass Door, page 22.

WARNING: The glass door must be securely in place before running this fireplace. Do not run this fireplace if glass is missing or broken.
