TJERNLUND
DRAFT CONTROLS
B Series:
Double Acting
Standard Control for Gas Heating
Appliances.
The Problem:
Heating appliances are designed to
operate with a consistent draft. Chimney
configurations, mechanical draft fans
and weather can cause draft fluctuations.
These fluctuations result in inefficient
combustion and more frequent service
calls.
The Solution:
Draft controls regulate the airflow through
a chimney or vent. By diluting the
chimney/vent draft with varying amounts
of room air they maintain the draft at a
heater’s flue outlet within a consistent,
safe and efficient range.
