Introduction Product Description Audience The ImmersoPak burner (IP Series) is a nozzle-mix This manual has been written for people who are already burner with a packaged combustion air blower that is familiar with all aspects of a nozzle-mix burner and its designed to fire on-ratio (proportional air/gas control) or add-on components, also referred to as “the burner fixed air on smaller models over a turndown of 10:1.
Safety Important notices which help provide safe burner operation will be found in this section. To avoid personal NOTICE injury and damage to the property or facility, the following warnings must be observed. All involved personnel should ■ This manual provides information regarding the read this entire manual carefully before attempting to start use of these burners for their specific design or operate this system.
Installation Gas Piping In this section you will find the information and instructions that you need to install the burner. All the gas piping must comply with all applicable local Handling codes and/or standards such as: • Make sure that the area is clean. •...
Checklist Before Installation Tank wall Intake Make sure that the wall of the tank is strong enough to To admit fresh combustion air from outdoors, provide an carry the weight of the burner. If necessary, reinforce the opening in the room of at least one square inch per 4,000 tank wall area where you plan to install the burner.
Control Motor For detailed information on how to install and connect a UV scanner, refer to scanner information guide. Install a control motor to modulate the air butterfly valve if Flame Rod not previously installed on the burner. If the flame rod option was selected when the burner was ordered, the burner will be delivered with the flame rod already installed on the burner.
Adjustment, Start and Stop In this chapter you will find instructions on how to adjust a system, and how to start and stop a system. WARNING ■ Gas inlet pressures must stay within the specified DANGER range. Pressure above the specified range can damage the ratio regulator.
Step 2: Verify Air Flow 1. Start combustion air blower. Tap "A" 2. Drive control motor to low fire position. Fixed Air (Options 1,3 & 4) 3. Set low fire air. a.Loosen the set screw on burner side of coupling .

Procedure B: Fixed Air NOTE: If viewing the flame, it should be blue with flashes (High/Low or High/Off) of yellow. When firing propane or butane, a proper low fire flame may have sustained flashes of yellow. 1. Be sure combustion air blower is running. 9.
NOTE: Gas pressure at low fire will be too low to measure and verify the fuel settings. 6. Cycle burner from high to low (if applicable) several times to check repeatability of settings. 7. Readjust burner if the settings do not repeat as expected.
Maintenance and Troubleshooting Yearly Checklist This chapter is divided into two sections: 1. Test (leak test) safety shut-off valves for tightness of • Maintenance procedures closure. • Troubleshooting guide 2. Test air pressure switch settings by checking switch Maintenance movements against pressure settings and comparing Preventive maintenance is the key to a reliable, safe and with actual impulse pressure.
The nozzle and combustion tube/block can be inspected without removing the burner from the chamber wall or entering the chamber. Perform the following: a.Shut the burner off and manually close the main gas shut off cocks. b.Allow the chamber temperature to cool down to 250°F (121°C).
