DRAFT CONTROL INSTALLATION IN TYPE B VENT PIPE

CAUTION: DO NOT use the supplied collar when mounting draft control to Type B Vent Pipe. Install by using a Type B Vent Pipe Tee.

1. Install a vent pipe reducer or increaser into the inner pipe and fasten using sheet metal screws. (See Figures 6 & 7)

2. The opening of the Type B Vent Tee, at the draft control mounting location, should be sealed with a high temper- ature sealant or equivalent.

3. Refer to Insertion of Draft Control Section.

INSERTION OF DRAFT CONTROL SECTION

Insert the draft control into the collar or tee. The front face of the control MUST be plumb and the bearing surfaces MUST be level whether the control is on a horizontal, vertical or sloping flue pipe. Use a spirit level and level accurately. (See Figures 6 & 7) Secure the control in the collar by tightening the clamping screws. If a tee is used or a collar is supplied locally, the control may be held in place by sheet metal screws.

ADJUSTING THE DRAFT CONTROL WITH 4" MG1

The control MUST be adjusted to the desired draft setting by adding or removing the washer-type weights supported by the two chains on the side of the draft control. (See Figure 8) DO NOT move the weight attached directly to the gate, this is used only for balancing at the factory.

ADJUSTING THE DRAFT CONTROL WITH 5" AF

Vertical Flues Mounting - The control is shipped for installation in a vertical flue. The adjustment weight should be in the right hand slot when you face the control. See Figure 9.

Horizontal Flues Mounting - For hori-zontal flues, remove the weight from the right hand slot and attach it to the left hand slot as shown in Figure 9.

What Draft Setting to Use - When adjusting the control, two things are essential:

1. The burner must be operating for at least 10 minutes to obtain maximum chimney draft.

2. An analysis of the flue gases is necessary to determine the

percentage of CO2 and check for presence of CO. Refer to the appliance instructions and/or to the local gas company for the proper CO2 readings and allowable CO levels. A rule of thumb for draft setting is between .01" to .03" of water column draft at the appliance outlet. (Check equipment requirement.)

Changes in the adjustment of the 4" MG1 control should be made by adding or removing the washer-like weights (supplied with the control) to or from the weight holder chain assembly. After the control is adjusted, it's action will be entirely automatic, the gate will open or close by itself to correct for changes in the draft that occur in the chimney.
