Introduction - Bradford White Condensing PV Series Service Manual

Condensing PV Series

Introduction

The new Bradford White residential condensing water heaters are designed to provide reliable performance
with enhanced standard features. New design features include reliable spark to pilot ignition system,
enhanced diagnostics, simplified servicing, significantly quiet operation and additional vent lengths.
Spark to Pilot Ignition System - employing the spark to pilot ignition system promotes reliable and consistent
pilot and main burner ignitions to provide hot water on demand.
Integrated Immersion Thermostat/Gas Control Valve with LED - was developed for ease of troubleshooting
by providing simple diagnostic codes to pinpoint an installation or component performance issue.
New Powerful Blower - will eliminate problems with difficult venting situations.
Quieter and Cooler Blower Operation - blower noise is significantly reduced for both interior and exterior
environments. Cooler operation increases blower life by reducing bearing wear and noise.
Rugged Wiring Connections - receptacle type connections promote error free wiring.
Increased Vent Lengths - increased venting performance is achieved while achieving 90% Thermal
Efficiency and enhanced Standby Loss performance.
The residential condensing water heaters use a combustion system where the flue gases are pulled at a low
temperature from the water heater directly into the blower. The flue gases are evacuated to the exterior
through low temperature vent materials. The gas control maintains water temperature, ignition sequence
and regulates gas flow. A safety circuit consisting of a pressure switch and blower temperature switch
verifies proper conditions exist for safe and reliable operation. If a situation outside of normal operating
parameters exists, the gas control diagnostic LED will flash a code to positively identify an operational issue.
This service manual is designed to facilitate problem diagnosis and enhance service efficiency.
Please read the service manual completely before attempting service on this new series of condensing
power vent models.
