Manifold Pressure: 4.5" w.c. natural gas, 10.0" w.c. L.P.

Gas Supply Pressure: At least 1" above manifold pressure with water heater operating, 14" w.c. maximum

PDV-S MODELS:

Power vented through either 3" or 4" diameter PVC, CPVC, or ABS pipe for 150,000 or 199,999 Btu/hr. models, 4" only for 250,000 Btu/hr. models. Refer to the installation instruction manual for further information on venting lengths and installation requirements.

PDV-T MODELS:

Power vented through Co-axial Venting (pipe inside a pipe) - Combustion air enters from the outside the building through an outer pipe (200mm diam.) and exhausts flue products through the inside pipe (130mm diam.). Refer to the installation instruction manual for further information on venting lengths and installation requirements.

INDUCED DRAFT MODELS:

Connect 8” vent to blower vent collar for venting through a chimney or type B vent only. Vertical venting only.

30" Front Clearance, 16" Top, 2" Sides and Rear

150 PSI

Redundant thermister with 11,900 + or - 0.5% ohms resistance at 70 deg. F. Sensor inside well for lower sensor. PDV-T model series and Induced Draft models also use an upper sensor (dual sensors for these models).

Honeywell Integrated Control Board for Temperature Control, Induced Draft Blower, and Ignition Control Functions. Operates on 24 volts AC current from transformer. Single sensor boards for PDV-S models and dual sensor boards for PDV-T models and Induced Draft models.

Honeywell LCD Control Display with Temperature Setpoint, Format, and Error Code Display in User Mode, Diagnostic Functions in Service Mode. Communicates with Control Board. 24 volts AC. Same control display used on all models.
