2.1.1.5 HX50 Heat Xchangers™
A Pureheat™ Hydronic Air Heater equipped with HX50 Heat Xchangers
TM
and 4-Port Remote Manifolds
should conform to the following system configurations:
Connect the Four (4) 4-Port Remote Manifolds utilizing any combination [50 ft (15 m) or 100
ft (30 m)] of Circulation Hoses with a maximum overall horizontal run not to exceed 150 ft
(45 m) for each 4-Port Remote Manifold.
The maximum vertical rise or drop from the Pureheat to each Xchanger
TM
or 4-Port Remote
Manifolds is 60 ft one way from base unit.
Connect Four (4) HX50 Heat Xchangers
TM
to each of the Four (4) 4-Port Remote
Manifolds utilizing the 40 ft (12 m) 1/2 in. ID Black Circulation Hoses mounted on the
HX50 Heat Xchangers
TM
.
2.1.1.6 HX50 Heat Xchangers™ with Booster Pump
A Pureheat™ Air Heater equipped with the HX50 Heat Xchangers™, 4-Port Remote Manifolds, optional
Booster Pump and Auxiliary Pump Panel should conform to the following system configurations:
Connect the Four (4) 4-Port Remote Manifolds utilizing any combination [50 ft (15 m), 100 ft
(30 m) or 200 ft (61 m)] of Circulation Hoses with a maximum overall horizontal run not to
exceed 350 ft (106 m) for each 4-Port Remote Manifold.
The maximum vertical rise or drop from the Pureheat to each Xchanger
TM
or 4-Port Remote
Manifold is 100 ft (30 m) one way from base unit.
Connect the Four (4) HX50 Heat Xchangers
TM
to each of the Four (4) 4-Port Remote
Manifolds utilizing the 40 ft (12 m) 1/2 in. ID Black Circulation Hoses mounted on the
HX50 Heat Xchangers
TM
.
2.1.1.7 Maximum Heat Xchanger™ Connection Capability
Connecting the maximum number of Heat Xchangers™ will
not increase the heat delivered to the space
(compared to above stated standard configurations) but will provide increased air circulation.
All Pureheat™ Hydronic Air Heaters are equipped with a 5-Port On-Board Manifold (Circulation Hoses
connection points) capable of a maximum connection of five (5) HX200 Heat Xchangers™, ten (10)
HX100 Heat Xchangers™ with Five (5) 4-Port Remote Manifolds, and twenty (20) HX50 Heat
Xchangers™ with Five (5) 4-Port Remote Manifolds.
2.1.2 Optional Booster Pump
All Pureheat™ Hydronic Air Heaters are equipped to accept an optional Booster Pump which requires the
use of an Auxiliary Pump Panel for electrical connection to provide safety shutdown of the optional
Booster Pump. (For setup instructions, refer to Section 2.8, CONNECTING/DISCONNECTING
OPTIONAL BOOSTER PUMP.)
2.1.3 Circulation Hose Limitations
Do not
create excessively long Circulation Hoses by connecting multiple (more than two) Circulation
Hoses in series. Multiple QCs cause a loss of working pressure and restrict flow.
Regardless of length, no more than two (2) Supply Circulation Hoses should be connected in
series;
Regardless of length, no more than two (2) Return Circulation Hoses should be connected in
series;
Overall Supply and
Return Circulation Hoses should be no more than a combined 400 ft (122 m)
in length (with Main Pump);
Overall Supply and
Return Circulation Hoses should be no more than a combined 800 ft (244 m)
in length (with optional Booster Pump);
