Models marked -V can be used with the Newmac SVS sealed vent system.
Use burner air settings as a guide only. Set burner air to give a trace of smoke. Re-adjust burner air to reduce CO
2
by 1 to 1.5 percent.
Take measurements with the burner cover & air ducts installed (if any). The minimum recommended temperature rise is 65
o
F.
The maximum allowable temperature rise is 85
o
F. Select speed to suit specific installation requirements.
Air temperature can be lowered by increasing the blower speed, lowering the firing rate, or increasing supply & return outlets.
