RADIANT AND SNOW MELT APPLICATIONS

•

Typically the fluid circuit with the highest tempera-

ture and/or pressure should be connected to the left

side connections as indicated with the colored label.

• The circuit flows should be piped in a counterflow

arrangement.

• Use antifreeze specifically intended for hydronic

heating systems. Inhibited propylene glycol is rec-

ommended.

• Typical boiler water to glycol blend is 10% to 40%

depending on location and weather conditions.

Do not use automotive ethylene glycol or any undi-

luted or petroleum-based antifreeze. This can cause

severe personal injury, death or substantial proper-

ty damage.
