Pictured at right is a beautiful installation of four
Parker G2640R Hot Water boilers in the Telus
Building located in Prince George, British Colum-
bia. Telus, a phone utility, chose Parker due to
an excellent track record on previous jobs, high
reliability and efficiency. The boilers were sold
with a fully modulating lead lag system mounted
to one of the boilers.
The units replaced a single, much larger boiler.
Multiple boilers provides Telus with redundancy
and better overall turndown ratios. Because
these boilers feature highly efficient, sealed com-
bustion, energy savings are certain.
The boilers were sold by Murray Mechanical Sales
Inc. in Surrey, British Columbia. Engineering de-
sign was by Tom Miller with Morrison Hershfield.
Installation was performed by Glen Tasa, Central
Interior Piping & Maintenance LTD.
Pictured is a Parker Indirect Fired Low NOx
WH1900LGG. We have shipped many simi-
lar units this year for use in Bio Gas or Di-
gester Gas plants.
These units burn the waste gas if it is avail-
able, and have the ability to automatically
switch to Natural gas if the free fuel is not
available. The Indirect Fired Water Heater is
particularly well suited to these dirty gases
as the furnace runs at a warm temperature.

Parker Wins “Excellence In Exhibiting” Award
Long Beach, CA – The biennial Engineered Plumbing Ex-
position Show hosted by American Society of Plumbing Engi-
neers (ASPE) was held at the Long Beach Convention Center
October 27-28, 2008. The Engineered Plumbing Exposition
is the only event specifically for Commercial, Industrial, In-
stitutional and Commercial-Residential Plumbing Engineers,
Designers, Specifiers and Contractors.
After a last minute decision, we decided to display our 9.5
HP cutaway boiler for the first time at ASPE. As a result,
Parker Boiler was awarded with the “Excellence in Exhibiting”
plaque which we now proudly display in our lobby.
