GAS LINE SIZING
The gas supply piping for a single heater should be sized for a
maximum draw of 160000 BTU/hr /199000 BTU/hr for the
Greentherm 9800 SEO / SECO 199. Measure the length of the
gas supply line from the building's gas main to the heater and
use the section 6.1.1 and 6.1.2, page 17 or the gas line
manufacturer’s sizing tables to determine the pipe diameter
necessary. If there are more gas drawing appliances on the line,
size the gas line according to the total maximum amount of BTU
draw input rating of for all appliances combined.
Note: Undersizing the gas line may result in diminished hot
water flow rate and temperature. See chapter 6.6, page 25 for
the procedure to measure gas pressure. Proper gas pressure
must be confirmed at time of installation.
DANGER: Explosion hazard!
▶ If you detect a leak, shut off the gas.
Tighten appropriate fittings to stop leak.
Turn the gas on and check again with a
gas leak detection solution. Never test
for gas leaks using a match or flame.
