CLEARANCES TO COMBUSTIBLES A general clearance of 500 mm (20”) in every direction is recommended for servicing. In addition to this, it is very important to observe the minimum clearances to combustibles at all times to avoid any possibility of property damage or personal injury.
HANGERS INSTALLATION AND HEATER SUSPENSION The heater should be installed in accordance with the relevant provisions of National standards and Codes of Practice in the destination country. Suspension mechanism must allow for lateral tubing expansion. A minimum 300 mm (12") length welded link chain with a working load limit of at least 90 kg (200 lbs) is recommended (refer to Figure 5 for more details).
VENTING & COMBUSTION AIR General Requirements The heater should be installed in accordance with the relevant provisions of National Standards and Codes of Practice in the destination country. Heaters can be operated according to the following appliance type: Type A2. Gas appliance without flue gas system. The combustion air is taken from the installation space. Type B22.
Air Supply Air supply openings are required to admit air and shall be located below the radiant heaters. Exceptions are possible if the air supply openings are between the individual heaters and their location has been planned after proper evaluation of the air flow. The sum of the unobstructed cross-sections of all air supply openings shall not be smaller than the sum of the unobstructed cross-sections of all exhaust openings.
Supplying Fresh Air Step 1 Remove the four nuts securing the Inlet Cage to the Burner Box. Do not remove the Gasket and Choke Plate. Step 2 Secure the Inlet Connector using the four M6 nuts. Flue Gas Exhaust Step 1 Remove the Screen from the Fan outlet.
HERRINGBONE MANIFOLD SYSTEM The flue gas vacuum fan should position at the lowest point of the flue gas system. A condensate trap assembly must be provided at the end of the manifold system before the flue gas vacuum fan. To ensure that any condensation formed in the manifold is not trapped or allowed to drain back into the heater the manifold system should be arranged to fall slightly in the direction of the flue gas vacuum fan, 2 to 3 millimeters per meter.
GAS SUPPLY General Requirements Before connecting gas to the heater, check the supply gas and supply pressure: match the information on the rating plate of the heater. The gas meter and service must be sufficiently large to supply gas to the connected building gas load ...
ELECTRICAL WIRING General Requirements The electrical wiring to this heater must be installed in accordance with National Standards and Codes of Practice in the destination country. This appliance must be earthed. Electrical supply 230V, 50Hz Power consumption 70W (Herringbone 15W) Current rating 0.3 A Internal Wiring Diagram This is a two stage heater.
BURNER OPERATION Starting sequence of operation Turn the thermostat on. When the thermostat calls for heat, the fan motor will energize. After fan establishes the flow, the air-proving switch closes and activates the ignition sequence. The ignition module, after a pre-purge period of approximately 45 seconds, energizes the igniter. The gas valve opens after sparking starts.
ASSEMBLY INSTRUCTIONS SEQUENCE – PV L Step 1 The number of Hangers depends on the heater configuration; four to seven Hangers and Chains are required. All the chains must be aligned. Shortest chain length = 600 mm (Heaters 20 - 40 kW) 2800mm 3050mm Shortest chain length = 1000 mm (Heaters 50 kW)
Page 21
Step 6 Continue assembly by sliding Tubes through Hangers, and attaching all Couplings. Flanged Tube Length 3050mm (10’) 3050mm (10’) 3050mm (10’) 2800mm to (9’) Baffle Coupling Flanged Tube (Combustion) Gasket Tube (Heat Burner Exchanger) Choke Plate (Burner) Hangers Close all chain links “S” hooks, “J” bolts and turnbuckles or any open connection.

Step 14 Reflector overlap orientations: PVL 20LS PVL 20/30 Step 15 Install the End Caps using U-clips. Step 16 Install Reflector Brackets (two parts that centralize the Tube within the Reflector). Refer to the diagram below for Free and Locked orientations.
Page 24
Step 17 Wherever the Reflectors are overlapping, the Bracket must lock them together, except for the first overlap. Refer to the diagram below. Reflector Overlap Step 18 Attach Coupling to end of last tube and attach Fan. Orient Coupling and torque as described in Step 5. Connectors Cable Step 19...
ASSEMBLY INSTRUCTIONS SEQUENCE – PV U Step 1 The number of Hangers depends on the heater configuration; two or three Hangers are required (consisting of a hanger kit and chain). All the chains must be aligned. Shortest chain length = 600 mm (Heaters 20 - 40 kW) 230mm (9”) 2670mm (105”) 230mm (9”)
Page 26
Step 2 Fasten the Tubes to the Hangers using the supplied U-bolts and nuts. Refer to Step 3 for number of nuts required on each Hanger. Ensure that the Tube’s weld seam faces downwards. Leave nuts finger tight until the end of assembly. 230mm (9”) Step 3 Circled U-bolts require four nuts,...
Page 27
Step 6 Orient the Couplings to the 10 or 2 o’clock positions for nut accessibility. This will also prevent interference with the Reflector. Torque nuts to 20 – 35Nm. Step 7 Continue assembly by sliding Tubes through Hangers, and attaching all Couplings. Tube Length 3050mm (10’) Or 1525mm (5’)
Page 28
Step 9 Twist the Turbulators 90 degrees to lock them together. Step 10 Turbulators are ready to be inserted into the Tubes. Step 11 Bend Turbulator Tab down, tightly over the edge of the Tube. Step 12 The reflectors will overlap each other as pictured here.
Page 29
Step 14 Insert Reflector’s edge flange under the Middle Reflector Locator (detail in next step). Step 15 Repeat the above step for the second Reflector. Follow the same overlap sequence for the opposite side. Step 16 Install Side Reflector Locators. Refer to next step for details.
